Is the Kab Speedstrobe necessary with the VPI SDS?

I'll second that Narrod. Although $80.00 for a 10 inch plastic disc and a cheap box with a strobe light seemed pretty hard to swallow at first sight, now that I've got it I don't know how I ever lived without it.

Piece of mind. That's what it is. Piece of mind.

I think you just answered your question Lornoah. LOL
