I am switching my 3/32 set-up to 1/8" for my Track Bike. The bike I purchased is new and I have raced about 10 times on it and perhaps 1 or 2 seperate training rides in the track itself.
That said I am pretty ignorant to what Brand or specific chain would be best. Bear in mind that there are about 6-7 weeks left on my velodromes circuit so getting
something from overseas does not make sense.
Additionally I would guess something affordable would be the right direction.
