Chip is still around http://www.bikeradar.com/gear/article/interview-chip-howat-tubular-tire-expert-32128/, KTL too: http://www.engr.ku.edu/~kuktl/ (He's now the director).. and he's still active in racing mechanic clinics for USA Cycling... (as I wrote.. he's widely considered the authority in the US on the subject)

the article you linked to is interviewing him on his 1995 research, and the website has a '© 2006, Kurata Thermodynamics Laboratory, All Rights Reserved' on it, and doesnt even mention anything about tubular tyres.
development and improvement of materials is not taken into consideration here, and tufo was just introduced in 2001/2002 I think, I am going out on a limb here and assume Tufo found a day or two to improve its properties over the last 12 years. -

btw glue might be probably better, but I am sticking to tape as I heard a lot of positive comments irl, just proving your arguments are not really valid

So if you don't want to accept the results of research, advice from most of the cycling federations that have comissioned testing, a number of tire makers (such as Continental tire) .... and most of the mechanics of ProTour teams... and discount them all as "pensioners" and "not with it fogies"...

Tufo has been around for quite a long time. As TUFO they have been selling tires and tapes since 1991 but the tires existed well before that (as part of a state owned company).. If I'm not mistaken they used to be part of Barum (a brand which today belongs to Continental AG).. Barums were pretty popular at both the low and high end.. Anyway... glue tapes have been around "forever".. Its not rocket science.. I think the first tapes were probably from Jantex.. They are now in CX hotter than Tufo as they are thinner...
And tire advancements? Beyond nanoparticles (Black Chili) and synthetic fibers... The hotest tires in the peleton these days (Spring Classics) are cotton FMBs.. and they look like they could have come from Wolber... -

Calm down granddad, I was just enjoying the '...sticking to glue.' pun above.

The biggest issue with tape is that you can't sniff it.
Now that obvious joke = obvious is out of the way, what's a good set of tires that doesn't puncture too fast? Wiggle reviews are kinda mixed, bar on the very expensive tubs.
£60 for 1 tire, i'd better be the dogs proverbials.

what's a good set of tires that doesn't puncture too fast?
Anything filled with sealant.

"...What's a good set of tires that doesn't puncture too fast?"
What do you need it for... type of riding, terrain, weekly millage and so on? For most riders a good set of tyres will easily last you a couple of seasons. Can strongly recommend Vittoria Corsa Evo CX and Vittoria Triathlon Evo respectively myself.

Anything filled with sealant.
Trouble is, the sealant dries out and forms a solid lump of latex after a while. What constitutes 'a while' will depend on various factors, such as temperature and humidity, but end up having a lump of latex rattling around your tubs could prove annoying. Even the manufacturers of Stans fluid recommend topping it up now and again, before it goes solid, and if (like me) you're using valve extenders then this is potentially a bit tricky.
Which is why I'm still umming and ahhing about putting sealant in the tubs for my new road bike...

isnt the whole trick to rough the tyre from inside so the sealant grips and sticks to it though?

Haven't read all the replies, but here's my tuppence worth. I would advise against tape, especially tufo (if it's the extreme you are talking about) for two reasons.
- I had some on a set of wheels I bought, and I would not like to have to get the shit off at the side of the road.
- You don't have that few, sticky minutes after fitting a tub with glue to get the tyre seated nicely.
Oh, and I don't have a garage either, I used to stick the wheel in my turbo trainer sat on a mat, but I have just sold it without thinking...

If you use PitStop then you only squirt it in when you have a p_nctr, and it goes through valve extenders.

With the Jantex you can pull the tub back off the tape in order to line it up. I've not tried it since fitting mind- I'd hope that they are stuck on a bit more firmly now!
I've put quite a lot of sideways load through them and they don't appear to have moved at all.
Fingers crossed, anyway.
As I may have mentioned my road bike tyres are glued on.

It seems certain things starting with a p are a bit like "that play"
So the tubs are for a vintage Ciocc. It won't therefore see massive action due to the fact Northern Ireland has a climate, but no weather...
The issue is though that any route I take (3.5 miles to work. 7.5 miles other way) has GlassBin Belfast routes.
I saw the recommended Vittoria tires but they are a tad expensive, and I don't mind if the tubs are a bit heavier as long as they stop "those things".
(sadly enough the Ciocc will be my first road bike, every bike so far has been progressively lighter. Titanium screws are a joke if you grew up on a steady diet of Dutch Roadster Rustbuckets weighing a good 38 lbs)

It's a bit tricky roughing up a tubular tyre on the inside...

Yep, that's the current plan. I was hoping to pre-load the tubs with sealant to help overcome my noob's fear of tubs, but I think I'll just have to apply Rule No. 5 and rely on some Pitstop. And a spare tub, just in case.

Main reason I commute 20 miles/day on tubs is to de-fear them.

that why I am giving them a go, too
this, and weight

In addition to the issues of rim attachment (strength, basetape seperation etc.) one should, I think, also consider performance: tape increases rolling resistance.
