Yep. sounds like you just are not used to front foot steering. This ruddering thing is very common with self taught riders and intermediates. Focus on riding centered. Look down from time to time and check to see if you are centered or if you have gotten back. You should have equal knee bend in both front and back leg. When initiating turns, try to make a conscious effort to shift forward so that the front knee is bent more than the back knee. Using fore-aft movements also will help you to ride dynamic and not get stuck in a static position which seems to be what is happening to you now.
Thanks, this sounds spot on (i'm self taught and intermediate i guess). i think the ruddering thing is a carry over from when i first learned how to link turns and had to speed check often to keep myself in control. i know my front leg tends to straighten out when im making hard turns at speed or when im in bumpy/mogul areas. i'll have to make that conscious effort to correct this when im out on the mountain this weekend.
