this is the first time I've heard someone say the Hyroad Pearl is just sliding on them. Maybe you should try a small surface change first to knock the shine off.

For me, I don't have a Hyroad Pearl but I have a Crossroad and a Defiant Soul above that. When I can see the Soul start to lose it's drive, I can switch to the Crossroad and make a small adjustment and be back on the strike train.

If you really want a new ball and keep the Hyroad Pearl the way it is, I'd say go with the Roto Grip Asylum that comes out shortly. It has a lower R.G. and I want to say a slightly stronger cover.

lightly knocked off the shine...gonna see what that does

If a hyroad pearl is not finishing I would investigate why before drilling another ball.

See if surface helps. That will tell a lot!!

Let us know

I would think your pro shop operator could give you some things to try.
I'm sure he drilled it to fit your game, so the not finishing must be a puzzle to him also.

Your comment about sliding in the back end puzzles me.  Hyroad Pearl is not a super strong ball, and it will labor for lower rev guys on heavy oil,  from deep inside, or when you are forced to cover a lot of boards.  If that is what you are seeing, then I would also suggest the byte.   If you really cant get it into a roll, then you have a surface issue, and probably should be looking at a solid ball.
