You say your scb is drilled modified leverage. Is this meaning that its not stacked leverage, yet not label leverage, or does this mean something else?
If you are really having that much trouble moving the ball, there is really not much stronger you can get than an scb in any type of leverage. The proprietor must have a lot of money, or, no offense, you must not have a lot of hand, because if there is really that much oil, all the machines will start having problems very quickly with that much oil. Plus, the expense of oiling every lane that heavily will take its tole on the profit sheets.
You say in your profile that you are a stroker, so maybe the pattern is more medium heavy, and you need to slow the ball down and try and put a few more revs on the ball? This would be the only suggestion i can make, sorry i couldn't be of more help.
