I've drilled all 3 up, and am extremely impressed with them so far.
The 715 has gotten the most use so far, it is fairly angular but it has such a revvy core, so it's still very controllable and versatile and I am much more comfortable throwing this ball then most other angular pieces i've owned. I'm really liking it on most medium to medium/heavier conditions as long as it has friction downlane. I did take the cover down 1000Grit and then re polished it because it seemed to have just a tad too much length for the fresh stuff.
The 930 is another quick revving core in it, but it's very strong and smooth downlane, tons of flare. It's not one of those hook at your feet type of ball, it's very comparable to the Virtual Gravity only hopefully it will last longer. I am really impressed that with surface and I cover a lot of boards and the ball still has soo much energy left at the pins.
The 505 is the newest and has the least amount of games on it but it is quickly becoming my favorite of the bunch. In box condition I found it to be a little too close to the 715 in overall hook but a little more even downlane so took the cover down to 4000 and now I have good separation between the two. This ball absolutely hooks though, even in oob it is much more ball then I expected. Very strong, very even, seems to very useable on lots of conditions and takes well to hand position changes.
I haven't thrown a Track ball since the Crash but I am loving the new stuff so far and they seem to doing very well around here.
