I am curious about your thoughts and experiences with pin axis drilled balls. What surface works best for you? I have two balls each drilled pin to pap 1 inch. One is a Roto Neptune and the other is a Mystic. I have always kept these shined up because my thoughts were that with the early flare from this drill might cause them to burn up too early, causing bad carry. I know the volume of oil present is a huge factor here, so lets assume a medium THS condition.

With the polished surface on these balls I sometimes have a problem getting them to finish, resulting in light hits, however I am a big fan of this drilling because of how easy it is to find the pocket when other more aggressive balls/drillings are over under or erratic at the breakpoint. Has anyone had success with a more aggressive surface on an axis drilling.

I think the biggest reason why you are having trouble getting them to finish is because the pin is too close to your axis.  You gain control at the sake of finish.  Adding surface will just exacerbate the issue because it will cause the ball to roll even earlier.  That type of drilling requires significant friction downlane to generate any kind of angle.  Never worked well for me on THS because of the buildup in the middle.

I think a better solution unfortunately is to go possibly 2-2.5" from the axis and go with a weighthole an equal distance below.  You still retain control but you get more angle downlane.
