It 100% depends on your style and expectations of the bike.
You being a mere 11 stone will make a difference too.
I think the issues arise from the fact that with the SB, the faster you go, the more active the suspension is. So people attempt a setup where they want "plush" and "small compliance" because people have the assumptions that these characteristics are the bestest, when in fact all they mean is that the suspension feels like it is doing something when you're bouncing about in the car park. Going for the "plush" setup means that it will use all the travel a bit easy. So the SB may not have those revered traits in the car park test, but when you go fast on rough terrain, it eats it up.
My shock setup at 13 stone comprises of ~20% sag (190psi) and a large air can spacer. The large air can spacer is there for bottom out prevention and mid stroke support. I use the bike for anything from xc poddles to uplift days and hucking, i just about use all the travel on ~5ft vertical drop on to flat ground with rough landing at high speed. The mid stroke support is there because im a BMXer, im looking for every opportunity to leave the ground, i need support.
My shock only ever feels harsh if im going too slow, so it acts as a physical prompt that im going too slow, just speed up and it'll take care of me.
The yeti recommended shock setup of 25% sag with no air can spacers resulted in a softer ride that did just about use all the travel on an average trail ride where i'd still be attempting any gaps or jumps i could find on the way. It however got bogged down a little at times and lost its pop/pump, it sort or became a bit of a monster truck slump.
Also, if you're looking at an SB, there is a lot of conflicting opinions for exactly what the bikes intent is, some see it as a burly trail bike, some see it, including myself as a scaled back mini DH bike. I feel that the confusion is there because it pedals so well, making it seem like a burly trail bike, but to myself, the weight/geo/stiffness/capability and composure in use says otherwise. The fact you can buy it off the shelf and tested with a coil shock says something too.
