I’m also about the same size as you MrFanny I’m 5′ 10″ with a 32″ inside leg. I currently ride an 18″ Stumpy HT but I also have an 18″ ETSX50. The HT is more XC so head down @rse up. The ETSX is more all mountain so slightly more upright as you would on a FS, however I have changed to a 80mm stem and an OS high rise handle bar cos I prefer it that way.
The ride is awesome with the 4, 4.5 or 5 inch adjustable travel front & rear. The spec is great with Fox TALAS forks & RP23 shock, Raceface kit, Formula K24 brakes etc. It climbs very well & descends even better I just need to learn to trust the bike & stay off the brakes more. I was apprehensive about spending the money on this bike but I haven’t been disappointed :D
I would recommend that if possible you ride an ETSX before splashing the cash as it may not be to your liking. Good luck & I hope you get one soon.
