I used one for a long time but then my four ball roller containing it, a Glowing Amulet, Uranium pearl, and another ball was stolen.
I liked the Blue Sparkle and the Burgundy Gryphons a lot but the G-3, not so much.
Those two were very hard hitting, great carrying balls that covered a wide array of conditions for me. My Burgundy was more for fresh true medium oil and I used the Scorcher for heavier stuff.
If I could find one cheap and a house that oils the lanes I'd buy it.
