I use a Vinci RV1923. its a 12.5 H-web and i love it. Cant go wrong with a Vinci or that pro prefered up top.
I've gotta disagree with the recommendations be made here. The OP is currently using a 13.5" Nokona. Those things play big!
My advice would be to go no smaller than 13" or 12.75". If you go much smaller than that you more than likely will feel uncomfortable with the glove. If you go with Vinci a glove like the BMB-L would be much more suitable for you. It's also a good size for both IF & OF play. A great 2-way glove!
