I've been practicing locally at a center that has been putting a shot at least close to Nationals and I believe I have a gap or two in my arsenal.
I have the follwing bowling balls set asaide for Nationals:
Nano pin above the ring
Eagle pin below the ring
Grand Illusion pin above the ring.
I have a Mega Friction pin above the ring that has given me a pretty look early on.
The gap I believe I have is between the Eagle and the Grand Illusion. Eagle is too strong step down to the Grand Illusion and it barely turns the corner.
PAP is 4 7/8 and 5/8 ip, ball speed is about 16.5 but measured 13.4 at the pin deck revs about 300.
Thanks for reading,
