@MEDDERX How much are you looking to spend on a ski upgrade? I have never ridden an A2, but I'm positive it will be a lot better than your current ski. You can also get even newer skis at a relatively low price on Ski It Again
I'm similar in size 5'8" about 135(?) I never weigh myself. The last few years I've been riding a 65" Radar Lithium Senate, then went to a 66" HO Syndicate V-Type, then switched back to the Radar in June. Recently tried a friend's Connelly GT, his was 67", but I liked it so much I bought a 66" Connelly GT and am really loving it. I've been skiing a lot this summer, but just ran my first couple of -32 passes @ 34mph last week on the 66" GT, so I'd say either a 65" or 66" ski will work just fine for you.
Have fun ski shopping, and if you get something on SIA that you don't like you can always sell it and try another one :)
