This. I LOVE my Scalpel. And at 23 lbs, there isn't a huge weight disadvantage over a hard tail. I race, but I also ride A LOT. No way am I going to a hard tail. The comfort of the FS is key for me. Does it climb great? Not entirely, but it's not a dog either. I do MTB rides for fun that are about 45 miles, with approx. 4000 ft of climb (or more) on the FS, and don't have an issue.
That said, everyone is different. You need to try the bikes to see what will work for you.
Oh, and yes my 29er corners well, but I totally get the point about it not being as responsive as a 26 inch wheeled bike.
