I shoot bows with long limbs. I usually prefer to pair these with a longer riser, as to stress the limb a little more and get a little more performance. With a typical 28" draw length, a shorter limb will PERFORM better, but not necessarily SHOOT better. If you're looking for performance, draw length and limb length go hand-in-hand. Longer bows are more forgiving, but there are benefits to both ends.
As many have said, shorter bows magnify the imperfections in your shooting form. However, a shorter limb will stress the working portion of the limb more and make for a more efficient bow. This being said, Jim's bows perform really well, so although you may notice a few FPS difference (if you're meticulous and chronograph your arrows) and possibly a cast difference, but chances are you will shoot the longer limbs better.
Good Luck!
