Which was the better fork. Girvin Vector or Amp Research ?
I rode a bike with a Girvin Vector fork for a bit in the mid 90's. I think
the elastomers could be upgraded to a coil or something. I'm trying to get my hands on a 1997 Stevenson Psychosis, a short travel high pivot suspension bike. A Girvin fork (with a coil spring ?) might be just the ticket, but I've always been curious about the AMP linkage forks. For those who've ridden both, which was the better fork ? Which was lighter ? How are they different ? Was one more reliable/durable than the other ?

I've kind of had both. I had an Amp F-2 back in the mid 90s, and when it worked it was a decent fork (for the day). I've also had a Noleen Crosslink (the girvin's younger brother), and definitely liked that one. Out of the two i listed, I would definitely go with the Crosslink. Unfortunately, I can't say anything about the Vector. I believe it was less good.
Everything under the head tube
Pivots wear out super quickly
Brake chatter (really bad!) when pivots start to go
Suspension action wasn't super plush or amazing
Fairly short travel
Reasonable amount of travel
the "ULM" (upper link mount) had to be in a specific location limiting handlebar position
Dual-crown style fork dented my frame on both sides
A bit heavier than the AMP, but not a heavy fork
