I wasn't sure where to post this but it seemed to be more of a frame builder question than a mechnic question so I thought I'd try it here first.

I've got a 1990 Trek 700 frameset with the chrome-moly main tubes and the hi-ten fork. The 730 of that year came with a chrome-moly fork. I can get a chrome-moly fork that is a nearly exact replacement for the original but I'm wondering just how much of a difference in weight, comfort and strength it would make to replace the hi-ten with chro-mo. The reason I ask is that the original fork received some cosmetic damage last summer and I'm looking at repainting it (too much damage for a decent touch up, but LBS says fork is structurally fine). I can upgrade to chro-mo for about $60 but I'm wondering if it is worth it.

Thanks
