Wanted: Campagnolo Cranks or Chainset?

Also got a set of Ofmega Strada retro cranks, copy of the old Campy fluted ones, 144 BCD, come with 2 x 42T and 1 x 52T 3/32 rings and a set of either single or double chainring bolts (your choice), 170mm and ISO (obviously) £25

not sure i want retro cranks, i want something that can take maximum punishment :)

50T Miche 3/32 chainring £10, or 50T 1/8 £18, both vgc/near new, 135mm BCD for Campy

A 50T miche would be perfecto, but i need the cranks first and whether its a set or not will tell.
