The Hope 31.8 bar is very stiff tbh- I’ve not ridden the 35 but “more compliant” is relative and the Hope’s one of the few that I’ve ever ridden that I’ve really gone “holy shit that is stiff”, along with my old Enves. Did not like.
I’ve ended up with a set of nukeproofs, a set of RSP Egos, and a set of Renthals, all 31.8mm and 780mm, and tbh they all fall into the “not so stiff or compliant that I really notice either way”. Not to say they’re the same but they all seem like happy mediums. Wouldn’t suggest any of them to anyone that actually wanted a compliant bar but maybe to someone that’d had a super-stiff one and just wanted something less extreme (like me!)
(also got a set of Cobalt 11s which are hilariously bendy- like voodoo on a rigid bike but it’d probably be horrendous on a big bike, they’re like rubber)
