Just drilled my Special (See my review). Best word to describe it: Continuous.
Used it on Brunswick ProAnvils, one oiled 35 buff to 38, other 40 buff to 45.
Once it picks up in the mid-lane, it does not stop. But great thing is it isn't jerky or snappy at all. I'm sure on longer or heavier patterns it will store more energy and be a bit snappier, but I can't see it being real jumpy due to the core/cover combo. Real nice compliment to the Thunderstruck,for me at least. Will update after using on some different patterns and surfaces. Real winner for those looking for a real even, strong midlane reaction and a strong (real strong) continuous backend.

If you blame the lane conditions for your bad scores, then you had better thank them for your good ones!!
