I can say the Shock is definitely stronger than advertised....I use mine on my 41ft 26ml THS and its great, but on my 38ft 17ml the ball never rolls out but picks up early and just keeps hooking....I can always find a line with it deep inside and even though it picks up early, it still goes through the pins like a truck. It a really nice ball, I have used it at 2000, 3000, 4000 and polished and the results are always great. It has turned me into a Motiv guy, now having 4 Motiv balls in the last 6 weeks....BTW, the Revolt is awesome if you have some volume too....
