I know this will sound like an advertisement, but look at the Martin line for longer draw draws. They have a couple bows that go up to 36" draw, depending on bow, limb, cam combination.

You don't say whether you're married, but depending on that you just don't realize that you got the world by the gonads. You still got lots of time to travel around and try all the new stuff out---and this out of necessity. There is another option if you're so set on a Switchback. 30.5" + a string loop. Or a twist or two in the cable. Man, you gota lot of options right in front of you. Of course, knowing me, I'd opt for a longer A2A to go along with that long draw, but with my 27" draw I still prefer a longer A2A.
