Wanting to try first Radical ball and can't decide if I should go with Pearl or solid, thanks any and all feed back appreciate.

I'm LH around 14.5mph, not a high rev guy, what I am looking for is something to play deeper on the lane. I start the night with my BW Legend and by the last game line is burnt ( 2nd arrow) but don't have anything allowing me to move in that will turn the corner and still get the 7pin out.

I would recommend the Yeti Uncaged for what your describing. I use mine for that type of situation/condition and have had good success with it.

I haven't done any to mine but if I remember correctly, from one of our conference calls, Tom Hess did change the surface on one of his and loved it.
If you are wanting to stay in the Reax line you could pick up the Gusto. I use mine when I run into lighter patterns or high friction surfaces.
