If you are going to go with the Delta handle make sure you get an 08, the 07 had a terrible grip that will be done for after just a few rides. The 08 grip is very comfy and seems durable, no chance to test that yet though.
I hated zeroG ... made my hand cramp and just wasn't nice to hold.... I came from using an ERA though, thicker grip...and went back to that right after I bought it
I never liked the foam grip handles. I think I am the only boarder that still looks for the rubber handles and a pair of gloves. I have been wakeboarding for 14 years now and that was all there was back in the day lol. I am just so used to it that that is just how I roll now.
