Ive got a Slash and generally find it an awesome bike. Its very nimble as people have said.
There are two downsides that you need to be aware of:
1. It seems to have a very low BB even when in the high settings – pedal strikes are common; riding deep rutted sections (e.g. at the Golfie) is a bit unsettling
2. Sometimes, it’s just too much bike. A 29er with 160mm travel is a helluva lot of bike, which sometimes dampens the trail too much, and hence dampens the fun.
I’ve ridden it at Dunkeld, Laggan and all over the Tweed Valley and it’s a fantastic bike. However, I rode it recently at Comrie Croft and found it to be just too tight up there for it – I felt like the bike was seriously hard work rather than the fun, poppy, twisty experience that I had when on previous 650B bikes. Maybe I’m just not skilled enough, but I’ve ridden there plenty of times and never felt this way about the place.
It climbs well for such a big bike but don’t expect it to be a fantastic climber – it’s too slack and big for that. However, the climbing is certainly worth it, stick it on the downhill trails at Inners for example and you’ll be grinning from ear to ear.
