George,
I too, being "newish" to tweaking, bout 3 1/2 months have found these DDB's to be easy to tweak...They also help me add a little weight to get up to 3.5 which is what we are currently playing down here.
I have to say, going to my first "tourney" style format last week at the Dixie league I encountered and saw an awful lot of speed diamonds "buzzing" around at GREAT speeds by some "names" in the hobby. I am still working on tweaking those bad boys, specifically to "bounce" off a DB...I witnessed it done to me many times. I believe they were tweaked by ChetDakota with his nephew John who just schooled me w/those bases and the sticks to the tune of 28-7. I'm open for hints from y'all
Is there a way to get your black bases with out being at an event with you?
