on almost every bowler this will be a 5-5 1/2 from Pap that will produce more length and a snappier backend...
if you want more backend you need to try some cover(surface) adjustments...
like the next options i will provide you.
Option 1:maybe you just need to hit it with a lower grit pad, the DB has a 2000 grit finish a 1000 finish will have more friction(but not necessarily more backed, it depends on bowlers revs speed and tilt, but try it could be your matching surface to produce more backend)
Option2: it could be that the ball is rolling to soon and spending the energy too soon, so maybe adding some polish over the BOX FINISH will be good(will not have as much friction or midlane roll, and it will delivery more energy on the back part of the lane)
Option 3: go for a low grit like 800 or 1000 and apply polish to have surface under the polish(this will give you length and recovery with continuation on the backend, for me this surface give me the same length as Box finish and more backend).
