In that case, get a hardtail 29er, you'll enjoy the ride. At your weight the main concern is making sure the fork is set appropriately for your weight. The RockShox XC32 (or XC28) forks have multiple stiffness springs, you'll want the shop to swap in a stiffer spring. Many of the cheaper Suntour forks only have one spring option, which means you'll be bottoming out a lot. Alternatively, air pressure forks are highly adjustable but generally more expensive.

You may also want 180mm rotors up front for the extra braking.
