I tried to play what I thought would be mulitpule different lines and equipment. For me, my best shot was swinging it. I was standing on 30 with my left foot, I would get it around 18 at the arrows, and push it out to 5-8 board. Anything out past 5, NO DRIVE! Anything inside 9, I was going left of head pin. I do put alot on it, (dont know rev count)if I had to compare to a pro, my form is alot like Tony Reyes but reaction of like a Pete Weber. Im not saying its exact, but somewheres close too. I was throwing a Rival with some surface on it. Drilled pin under ring finger, cg kicked out. I would suggest something that has length but something with finish at the same time. My Rival had more finish than my Black Widow did, and BW was polished. I dont think a dry lane ball is needed, but doesnt mean not to bring it because you never know.
I know if I went and practiced more than I have as of late, I know a 625+ series is very possible.
