^^^^ +1000 to what Tom said.
The Mono 29er is a great ride, in fact I really want one. Always have, just keep avoiding it for some reason.. go figure
. SS 29ers from those who I know who have 'em, are downright addictive.
That being said, unless you have the cash to drop on a wheel, either stay off road, and/or prepare for problems. The stock wheelset isn't up to those of our stature pounding on the bike. In that respect, the 26in Monocog might be a better choice for you.
Also, sizing wise the Redlines seem to almost run a little small. I rode a mono 29er in a 21in, and it was just about perfect. I ride a 19in Specialized Hardrock that's perfect, so YMMV. I'd say gunning for a 19 is a good number.
Ride what you'll ride, buy what you'll ride. Just remember that and you'll be good
