From Sheldon;
Biopace and Fixed Gear
People are often astonished to learn that I ride Biopace chainrings on fixed-gear bikes. They imagine that there will be tremendous changes in chain tension as the chainring rotates. In practice, this is not the case. A 42 tooth chainring will generally engage 21 teeth against 21 chain rollers, regardless of its shape. There is a slight variation in tension resulting from the varying angle between the two straight runs of chain as the axis of the chainring rotates, but this has not generally been of a sufficient magnitude to cause any problem in practice for me. -

I still have a crank puller that will do the job.
@ajf, if you're in Leeds, try Spa Cycles in Harrogate (they've got a whole load of TA/Stronglight stuff) -

Coppi, pah! Platini is right. Anquetil is the man.
