Before you pull the trigger, check out everything in the category. Make sure you check out a Tallboy LT, a Trek Remedy 29er, SB95, etc. There are tons of impressive bikes in this category of long travel trail/all mountain 29er right now, and while I'm sure the SB95 is an amazing bike, there are lots of options out there.
And with that, I know exactly what you mean. Right now this longerish travel hard tail 29er is working out for me, but in a few years when we move back west, I'll need more bike. But how many bikes remains to be the question.
