If you asked me this question 40 years ago I would have taken the 2", but now.....$30,000 looks to be the most useful choice because after all, I'd be the one impressed if I had 2" more because its used mostly for "wanking" and I don't need to impress "ME" at this stage of my life and my IQ is just fine for the same reason. Looks like age has a lot to do with the answer, at least in my case.
