Get someone to follow you and record your run. Or get a monopole and do it yourself. You'll learn a lot from watching what you're actually doing. For instance, I bet you aren't edging nearly as hard as you think you are, and I also suspect you are edging less on toeside than on heelside.
As for weighting, normally on a carve you start out weighted forward but you shift your weight back over the course of the carve. If you're keeping your weighting static, you're probably not as efficient over the whole carve as you'd like to be.
I'm sorry. Was I talking while you were interrupting?
