In my experience, every new generation of batteries from V4L seems to be a measurable improvement, and every time I am surprised they are better. The late 2009 vintage hardware was so much better then compared to what I migrated from, then the newer ash caps in 2011, then the diamonds, and now the Titans. The only exception to this rule IMO is with the autos - I actually liked the really old autos better than the diamonds, have not tried to the Titan autos, probably never will. I love the drip tips as well, and have also been enjoying the 2 ohm dual coil tanks - in this case, you really need to use the Titans of course
