I've got some "white lightning" bases : the fastest of all my bases.
THe DDB are great too : very easy to find strenght in them. The only thing with DDB is that I have to "push" it on the board sometimes to curl the hard sprongs better, and then...the base reveals all it power
Last thing, concerning speed diamond bases : on video tutorials George gave us he squeeze the prongs quite firmly, but be carefull because "quite firmly" can mean a lot of things depanding of your hand and/or pliers strenght
