In reaction to the local bowls copping the anti graffiti paint, and becoming way too slick as a result, I changed it up from F4 99’s, which I have been running since they came on to the market, to powerflex. They seem pretty good, just as quick as F4’s, no flat spots so far, and a little bit grippier, which is what I wanted. Prolly not that great for street, with the extra grip being unwanted in that scenario, but good for tranny and park.
Edit: bombed a couple of hills today with these and holy hell you’d wanna pony up before you sesh slide them, they grip like crazy!
