I just found a hammer backlash, and looked at it and it's in REALLY good condition so I decided to do some research on it, seems like it would be the perfect dry lane ball. It has something around 0.31 diff which I can't find in any ball today. Anyone have one of these back in the day? How'd it roll its the blue/silver one not the red/purple one
The Blue/Silver one is much rollier and smoother, almost urethane-like, than the Red/Purple one, which was longer with a more powerful backend.
Like Byars, I loved the Red/Purple one and found the Blue/SIlver one, although much better looking, of limited use. It handled more oil than the Red/Purple one too.
The Blue/Silver had the Max Control coverstock, while the Red/Purple one had the Max Length. The R/P was for light oil; the Blue/Silver was more for light-medium to medium oil, for me, who is rev dominant.
If you're speed dominant, you may find the Blue/Silver useful.
