I have both Balls. I got the one over a year ago and now it is my spare ball. I also use it on light oil. The Total NV , i shot yesterdat in my league for 686. Gotta say i was not on by any means , but the ball carried everything. Light hits, high hits , shots i didn't ripp to well. Plus shell was still at 4000 and on a medium to heavy oil the reaction was by no means monsteriuos.Can't wait to shoot ball later in the week ,as i change the coverstock down to 1000. Good Luck
