RE: Capiche 50
i wouldn't worry with the stiff carbon UC, I've got it and it just doesn't take out the landing knock at all. you can see the shock go up the legs, and I've got 3" foam wheels!!
Cartman has 2mm spring steel that absorbs really well and when he harriers it touches and has no danger of coming back up on the rebound.
I'm tempted to put a few holes to make it bendy near the top, but without knowing what I'm doing I'm liable to weaken it too much.
Dunno what the West 50 or Irvine 53 weigh, but the JE 56 is 360 grams. being a bored out 40 it should be super light.
