All of the above, actually, though I have to admit I tend to use V3 and S3 a lot.

And dangit, you took out this pack for V2 (if I recall right)  I was -still- debating to get just for that collar alone (the rest of your stuff in that pack would have been a marvellous bonus - yes, I'm crazy that way) LOL

anyway, whatever you decide to do, you'll have us jaw drapping, I'm pretty sure of it.
