Got a great deal from JB Bowling Supply in Henderson, NV on a Kingpin Gold that was too good to pass up.
Went 60 x 4 1/4 x 30 which is a pretty standard layout for me. I have to say I'm impressed.
I got it to fit between my DV8 Creed and Absolute Nirvana, it definitely seems like it'll fit that spot perfectly.
I've been skeptical of the dynamicore and other similar type items marketed from other companies. I have to say I did actually notice a slight difference which seemed to be more energy through the pins including a couple flying Messengers which I rarely see.
I'll definitely follow up when I get more games on it and a couple tournaments
