Before getting on staff with Lane #1 I pretty much threw 900G and Lane #1. I have owned 100s of bowling balls and those are the two brands I have matched up best with. I do have a Seismic Solaris Blackout stashed away that I never drilled after getting on staff, but haven't thrown any of their other balls either. I have tried the brands like Storm, Roto, Brunswick, Ebo, etc. and other than a handful of balls from Columbia and Ebo, haven't much luck with anything except the 900G coverstocks (which are also on Radical, Lane #1, Seismic, AMF). Unless you're on staff, I don't think limiting yourself to one company is a good bet if you want to really be successful. Sure, all companies come out with a full arsenal for the most part, but there are certain balls that really fit a niche that no other company might be able to produce. That's the reason I originally purchased the blackout, haven't seen a low rg solid with that med-low diff before from any other company.
If you do decide to go with one company, I would NOT recommend Radical; atleast not yet. They do make one hell of a ball (I loved the Slant) but all of the Slant balls are very strong for use on med-heavy oil for the most part and the Times Up balls are a lot of performance for the money. With only a handful of balls out so far, I don't think they've really put together a well-rounded arsenal yet.
