I consider myself very much a "stroker" in bowling style and I have no doubt, without spending about $200 to find out for sure, that the Timeless is not a fit for me. For bowling with high rev rates and 18 or higher MPH ball speed, it could be a great ball. Right now I am using the Alpha Crux, No Rules Pearl, Crux Pearl, and Pitch Blue in that order by lane condition from oily to dry, and I don't see anything among the other recent releases to justify replacing one of them with the Timeless, the Torrent, or the Code Black.
I will, however, be interested in seeing how the Sure Lock compares with the Alpha Crux. Being left-handed, I"ve had some great practice games on the right lane using the Snap Lock, where I can easily move my feet 4-5 boards over to compensate for the stronger hook of the ball. But on the left lane, trying to migrate over to the right in my approach (mirror opposite of what Pete Weber does on the right lane) is a bit of a challenge for someone whose skill level is orders of magnitude below that of PDW.
