I was in a dilemma years ago --- my race bike was completely trashed out (A PAramount PDG series full rigid) --- front suspension had been with us a few years but the world was just coming around to full suspension with AMP research, Pro Flex and others making light effective FS bikes

I was on a fixed budget,--- i really wanted to go Fs, but could only afford a framset , not a complete bike. I wound up buying a complete MArin Team bike, - full rigid Tange prestige steel. My thoughts were that i's rather have the boutique quality full rigid bike than piece together a nice frameset with a bunch of budget parts bin junk. The rigid MArin fork was "suspension corrected" so i could have swapped in a suspension fork at any time, --- but i never did

The rigid bike was light, responsive and fast ---- that said, at the time i was fit and flexible, but i rode and raced it everywhere ---
I'd get the Pine Mountain and not look back if i was in your shoes

--- but then again -- i might be a tad biased (same 1994 era MTB now does duty as a single speed -- talk about longevity )
