Actually normal geo 67/68 and a medium stem
Historically, there's nothing 'normal' about this - it's basically early 'progressive' and is the form modern XC bikes seem to be converging on - but with very short stems and longer wheelbases. So, then, progressive. IIRC my OG slackline had a head angle of around 68 which was considered wild back in 2011.
So yeah, just get a Chisel or whatever XC bike if you can't stomach what Speci do.
In my mind that would be like cotic geo 65 ISH head angle and then 30mm stem. Which isn't what you want for that riding. Actually normal geo 67/68 and a medium stem will be nicer for that style bike. So platypus suggestion is really good too, as those bikes will often be that geo.
