I don't know about the Jai Alai beers, but I do think that Bell's Two Hearted is very affected by age. It's a very fine beer when fresh, but it goes downhill quickly.
there has been a few times I've had super fresh Jai Alai on tap at the brewery and was pretty impressed. I feel it was much better way back when, before they expanded. Its kind of a joke for me, sometimes, the only decent offering at a restaurant or bar is Jai alai and I get it, yet my girlfriend will always say "I thought you were done with trying that one" I keep trying to like it.
I agree with you on 2HA - I had it once, less than a week old, chatting it up with Larry himself and it was definitely an incredible beer. That one degrades pretty quick. But I'd take it over JA any day.
