Total bow length is probably more important than riser/limb combinations. If you have a 30-inch draw, for example, you'll probably shoot a 62-64-inch recurve better than you will a 58- or 60-inch recurve, regardless of the riser/limb length combinations.
Of course, riser/limb length characteristics do have an influence. Larger riser bows may be a little more stable due to the greater mass in the riser. The additional weight makes them a little easier to hold on target and/or they're affected/thrown off a little less by poor releases, etc. On the other hand, they're bulkier and heavier, and not everyone wants or needs the additional weight.
And, of course, personal preference comes into play as well as far as what one likes to look at and carry. Tradeoffs, tradeoffs. Good luck.
