I don't know how all the urethane balls line up, but I do have a Super Natural and a Grenade. The house I bowl league in has old wood and as of late, my go to balls are the Ride and Joy Ride, and have been flipflopping the third ball, trying to find that right one. Anything strong will hook off the lane.
Have been using the Super Natural (sanded 500 grit) and have had some very good results, but inconsistent. Yesterday, I took out the SN from my bag and put in the polished Grenade (drilled RICO) that I haven't used in about a year. Oh my, the Grenade was great last night, very smooth with a nice walk into the pocket (usually) and the carry was good! I kind of want to try a Pitch Blue or Pitch Black but will hold off and try to keep using the Grenade for now.
