Got to use the new Black Diamond Particle Pearls tuesday night(5/17/11). The Pin-down Version for me is basically a carbon-copy of my Pin-Down Sting and the Label-Leverage Version reacts very similar to my original Sting which was also drilled Label-Leverage. It's amazing how close these two are to my current and previously owned Stings. Not saying it's a bad thing but I am glad I drilled the one Label-Leverage because I really regret giving my old Sting to my brother and this a perfect replacement for it.
Pin carry is typical of the Dynasty weightblock, track flare for me on the Pin-Down Version is close to around 5-1/2" (it's rated at 7") and around 4" - 4-1/2" on the Label-Leverage Version which is pretty good for me based on my release. As previously stated in early comments, the Pin-Down Version is much more aggressive early where as the Label-Leverage Version can be projected down lane a little easier.
I plan on throwing them this evening after league play to see how they react on a little bit of carrydown (which is where the particle pearl coverstock should accel). I also plan on changing the coverstocks this evening with a little polish to see what effect it has on them and will report out later.
Looks to me like another fine addition from Lane Masters.
