I was riding BBS/Generator pretty much exclusively for about 5 or so years (except for a few Northern Co's when they're available) and have been really underwhelmed by my last few boards.
My Traffic snapped after 3 days, wood felt real dry. My other, a Polar, lost its shape after a week and the wood felt dead and soggy.. it also chipped a hell of a lot more than any Generator board I've ever had. The last, another Polar, snapped after about 3 hours, wood felt super dry and brittle. The Traffic might have been a little old (got it on sale), but the last two Polar's were from new releases/batches. I had a Killing Floor which I LOVED skating (fantastic shape), but after a week or two the board became soft and soggy. Sucks because I love the Polar and Killing Floor shapes. Is it me, or has anyone noticed a decline in quality in the last year?
I got a Northern Co (either Pennswood or South Central... this one http://imgur.com/a/sGpa3 ) and the wood feels waaaay stiffer than anything I've got from Generator in the last year. It is un-chippable and my 195-lb ass hasn't even come close to snapping it. Only reason I'm not skating now is due to an injury.
The only thing I've skated, pretty much is Polar for the last 2-3 years, and I haven't noticed a changed. The board I had before the one I'm skating now lasted me two months (though I skated it death), and the one before that lasted about a month before I felt like moving on.
I break boards like crazy, and when I switched to Polar it stopped. I've cracked boards, and kept skating them for weeks.
In between, I've tried Quasi, FA, 3D, Chocolate (20 year edition PS Stix), Random DLX wood, Cliche, Welcome, Deathwish, and none of them came close. Most of these boards didn't last more than a couple sessions, including 4 boards in one month (two 3Ds, 1 Anti-Hero, and shop FTC board), and then went back to Polar. In 18 years of skating, I don't think I've ever found better boards.
Right now, I'm fiending for some kind of sale so I can stock up, again.
