I bought a Yeti 575 this year, whilst waiting delivery I borrowed one for a day in Cwmcarn, it was terrible!! Hated the thing wouldn't grip up hill felt crap down hill, i spent more time pushing (and swearing). Too late to cancel my order I built mine up admittedly with a fox 36 wound down to 140mm instead of revs and all my other bits and I can truly say it's the best bike I ever ridden (and my god I've had a few!) So IMO just faff with setup it's amazing even the smallest adjustments really make a difference every aspect of riding! Just carry a trail tool with the relevant allen keys.
