I've spent the last 2 years building my arsenal, and I really like what I have.  All I'm looking for is any gaps you see...I'll list from heaviest to lightest oil:

Paradigm Passion:  Drilled 4.5 x 4.5(mb), pin under bridge
Dimension:  drilled 4.5 x 3(cg), pin in ring
Gravity Shift:  drilled 4.5 x 4.5 (mb), pin under bridge
Pyro:  drilled something like 4.75 x 4, pin over bridge
T-Road Pearl:  RICO, making it roughly 4.75 x 4
Roto-Grip Neptune:  drilled 4.5 x 3, pin under
Spare:  CGmaddah

The way I built it was have the reaction shape alternate each ball:  rolly, straighter, rolly, straighter, rolly, straighter.  I was thinking that I want at least one more ball:  a hook / set ball.  I'm still trying to find what that could be and how I can find it, but that's something I'd like to get.  And also, maybe a weaker solid.

What do you folks think?

Weaker Solid was my thought.  I have been happy with my T-Road Solid at 4000 laid out at 5x3.  I know that OOTB this is a strong ball - but with the finish and layout it has proven to be a great lighter oil solid.
