Thanks all!
@DAWRX buying a FS is definitely the sensible call since I have fairly great downhill (ski lift served and ride up, both) near me. Was looking at the Marin Rift Zone, Kona Process 134, Giant Stance, and Rocky mountain thunderbolt. All "cheap FS" (LOL) $1500-2500 which is pushing my (college student) budget a bit, but I haven't found a type of riding I don't love so it seems like a decent possibility for next summer.
@jayvincent I may well do that... the idea of buying a $600 frame and slowly building it out over a few months seems more palatable than buying another bike (I have a gravel aluminum Kona Rove rn and love it, probably keeping that one forever). And I really like the idea of pieceing together exactly what I want-the full Sutra build is $2400 and has a ton of stuff I probably wouldn't use on a rigid bike like 2.2" tires and a dropper post.
@Bloody-the-resident-shitposting-saffer That would 100% be the most logical plan, but I've kind of found for gentle trails I prefer a fully rigid bike (my e-bike commuter is a hardtail, albeit a very heavy one, and I don't love pedaling with the fork unlocked). And the proper aggressive trails around me would be only doable on an FS-which is a bit beyond my skills and wallet to build haha!
