I've already had all my balance holes filled. I did a lot of experimenting with dual angles and have tried some new layouts based on Mo Pinel videos I've watched on YouTube.

I'm a high track player and avoided some layouts because I feared they would hook too early or roll out, but that hasn't happened. I bought a Roto Grip IDOL and drilled it with a 4 inch pin to PAP and a 40 degree VAL angle. It works well except from deep inside. I'm going to take one of my old Hy-Roads and drill in with a 3-3/8 inch pin to PAP and a 25 degree VAL angle and see what happens.

I'm finding I can buy weaker coverstocks and drill them stronger if I want the ball to go longer or buy aggressive coverstocks and drill them weaker if I want them to read the lanes earlier. I was a
50 x 5 x 50 person but now everything I own is less than 4 x less than 40 degrees.

I would think that any center that installed 'Specto' could charge enough to pay for the system. However, based on the number of centers who have it, there must be something else that's making proprietors stay away. I'm assuming cost, but it might be something else. There's not a single center in CA with it.
