Again, in true fashion of suggest what you own. Have you considered Starling bikes? The murmur is 140mm rear and a 29″ (They do a swoop which has 160mm of rear travel and 27.5″ wheels). The murmur would be pretty close to what you’re after and handmade in Bristol by Joe, you can get in contact and he’ll be able to arrange a demo.
I have owned a 2014 Orange 5 and a 2017 Santa Cruz nomad, although I liked those two too, I prefer the feel of the Starling (Steel). The Orange was good fun but a little short / small in a 17″ / M, I am about 179cm / 5ft 10″. However, I think they no longer do that sizing, and may just mainly be available in an 18″
