Hey Bruce,
I would reccommend 2 balls. First being the Silver Streak solid. It is a very smooth arcing ball that will give you great reads on med oiled lanes with some nice backends, with the out of box finish(polished). But what makes the Silver streak so great is its versatility is that the silver streak sands nicely and can easily be used a med oil piece.
The other reccomendation would be the retro ressurection. It has the same versatilty coverstock wise as the silver streak, but it has a stronger reaction. But I have seen this ball work dulled or shined. They are both GREAT pieces. Welcome to Roto Grip, I have learned to love them!!!!!!
