Yeah, waiting for the "downsizing" of popular boards is a dicey and frustrating process. You have the Skate Banana, which launched narrow versions of the 48 and 51 on year 2, and now a women's on year 3, and then you have the Malolo, which did the 149 on year 4, and everyone else who....didn't.
One thing I will say is that it's getting easier to keep boards longer. I used to feel like I was missing something by riding the same board forever. But truly, with a banana, a reg camber, and a malolo, the tweaking process should be minimal for a few years (i hope.) i didn't even bother looking for a "new" atomic fallen angel when i wanted one. i found one on sale for cheap, because i knew the guts were the same. here's hoping when the dust settles, we can start saving a bit of $?
