Dave,
I draw 30 1/2" too, and have both a 60" MAV and a 62" SAV (a few years difference in the vintages). For me - it seems they are pretty much the same as far as draw, finger pinch, etc. - with just a slightly smoother feel on the 62" - but only slightly.
The small difference (2") in overall length though, does seem to handle better in those hunting situations - like tree stand or a ground blind. Just a small difference but it does help. With the 62" it seems like I am always have to keep the lower limb from hitting something. And as mentioned above - if you have to shoot a severe angle, the string tends to bump against your leg or tree stand on downward shots.
If you go with a PSA - the working limb length will be the same as a MA riser. I think you will find that you will like it. As suggested above - do the test drive to see how it feels for you.
All in all, I prefer my 60" SAV over the 62" MAV - but that's me ..........
