Your stuff is not half bad, and the other half is coming from you, so you're in good shape. I ride a lot of stuff I find on ebay and at local swaps. I'm about 5 11 and 160 and look for Burton Ultra Primes in the 162 and longer sizes, Burton 163 e-decks. The e-deck/e-series is a great starter deck, but I can recommend them any time there is new snow - I ride one all the time. I also have a nice 172 Nidecker that I bought at a local shop, which is a gas in mid season when I've got a few runs under me. Have fun and pay attention to the side cut radius of the boards you are scoping out.
The Blade Series boards from Donek look intriqing. The 170 has a waist width of 22.5. My edeck 163 is 22. (Sidecut radius on my e-deck is 9, Blade's is 12.25 - that is longer than my Nidecker.) I'd love to have the opp. to try 'em all!
