I am a new member to the Motiv family. I went to a "Test Drive" today and got to throw the Octane, Venom Shock and Jackal. The Jackal allowed me to play much further inside (stroker) than I have ever been able to before opening up the lane and roaring back to the pocket - I had to get one. I was also very impressed with the Venom Shock, very smooth for playing my usual up and in shot. The Octane would be more limited for me due to my higher rotation angle creating enough flip already. Mike from Motiv was excellent in working with me.
Even though I have a couple of medium, benchmark type balls working for me right now, I think the Sigma Sting will have to be my next Motiv ball after hearing so much praise about it here.
