The cover on the SS is a little stronger. I too have the same thing (both balls drilled pretty similar). For me, the SS appears to read the oil a little sooner and is more of a strong arc in comparison to the Gargoyle. For me, the Gargoyle is a more true skid/flip. Because the SS seems to read the lane a little sooner, it actually has a few more boards of overall hook as well. SO.......
Using the Gargoyle, if I am standing 25, looking to play 13 at the arrows and 7 at the breakpoint, I have to move into 27-28, play 15-16 out to 7 in order to use the SS.
Peace doesnt always have to be silent.
