Well,
AJ's right everything's a learning curve.

I personally use a bit of everything.
WX for sax, velo and wheels for flutes and violins and bases.
I tend to use the BC set when I'm programming. It gives me a pretty good idea about the way the sound will respond (hard to hold the WX and move the mouse at the same time ). But even then I often have to turn up the BC assigned wheel on my master controller (Can't blow into the BC all the time - makes my head spin).

I'd definitely get the BC set if I were you. It will enable you to play the sounds expressively and still use your keyboard to play.
WX' s going to be a bit of a pain at first. Even though I play some winds, it still took me a while to get comfortable with it and start playing, instead of cursing and fine tuning the parameters (sensitivity levels and all that stuff).

Anyway,
Thanks guys. I'm new to this forum (I normally hang out at "General Discussion")
Seeing familiar names like the VL70-m and the VL 150 made me feel right at home.
