After comparing the 913D2 to my current 910D2, same shaft, same 8.5* loft, I found that I was getting better distance and all around numbers with my 910.  The only difference I found that I liked was launch angle and I know that has something to do with the new weight system on the 913.  My question is, would I get a higher launch angle from my 910 by going to a heavier weight?  I currently have the 5g weight installed. 

Look forward to hearing some input.
