Is it me? the board? my stance?
I'm having an issue that I'm hoping I can get some help with.
Background: I started boarding around 1999, but only went for 2-3 days every 2 years on average until this year (was living in Florida). Last summer I moved to Idaho and at the beginning of the season my husband and I decided to bite the bullet and buy our own gear for snowboarding. I am 5'6", 115lbs, and wear a 7.5 boot and I got Vans Encore boots, Salomon Grace bindings, and Ride Rapture board (151cm). At the start of this season I was just starting to reliably link turns on green runs. Now I can tackle most blue runs (at any of the 4 resorts we've been to), though I still don't have the speed that my husband or our friends do.
Problem: my board will not turn easily for me compared to other boards I've ridden. I hadn't really noticed this until I traded boards with my brother's girlfriend a couple of weeks ago to see if she would have an easier time on mine than her rental board. The rental board was a pretty stiff 152cm Ride camber model. I noticed that I found it a good bit easier to turn that my own board and my brother's GF found my board so tough to turn that she barely made it down the run. I assumed this was mostly just her being a beginner but had the same result when I traded boards with a friend earlier this week. Her board is a 153cm 2009 Atomic Hatchet. Again, I found her board very easy to turn while she found mine difficult (she's a much better rider than me, and I did not tell her about my turning issue before trading boards with her).
I'm fulling willing to accept that this is an issue in the way I am riding and not the board itself but the fact that two other people have had the same problem (and that I found their boards easier to turn even though they were larger) makes me wonder what exactly is going on. I went in to the first switch really expecting to find the board a lot more difficult to manage than my own, so I don't think it was just my expectations playing with my head. I don't notice it being an issue more for one type of turn than the other. The best way I can describe it is that it feels like the board is not responding to the pressure on my front foot the way that the other boards did.
So what's the deal here? Is there something that should make this board more difficult for me to manage? Or could there be something about the way I have my stance set up that is causing it? I've got my front foot at 15 degrees and the back at 6, though I started with duck stance (15/-15) tried several things in between and ultimately settled on 15/6. Alternately, is there some mistake I am likely making in my riding that would cause more problems on this board than the others?
I'm planning to do a couple of lessons this season and will obviously be asking this question then as well but I figured it could not hurt to ask here as well.
