was looking for a quick release for the stedicam pilot ... cause taking the plate off and then having to inscrew the bolt [which i am hoping not to loose one day] can and is a bit much specially if u need to go to say tripod or just to hand hold quickly ... any suggestions i dont see anything offered from tiffen

here's what I use....

Bogen Manfrotto Rapid Connect Adapter Assembly W/Sliding Mounting Plate 577 (http://www.digitalfotoclub.com/product-features.asp?id=964610812)

I use the same thing, here is a link from B&H
Bogen / Manfrotto | 577 Quick Release Adapter Assembly | 577 (http://www.bhphotovideo.com/c/product/241139-REG/Bogen_Manfrotto_577_577_Quick_Release_Adapter.html)

I also use the Bogen 577 as it's compatible with my tripods and other gear. You may also want to cut out the foam in your "backpack" so that the sled with QR adapter fits for storing away.

Ditto for me. I got mine here:
Amazon.com: Manfrotto 577 Rapid Connect Adapter w/Sliding Mounting Plate (3433PL): Electronics (http://www.amazon.com/Manfrotto-577-Connect-Adapter-Mounting/dp/B00009XV3M/ref=pd_bbs_sr_1?ie=UTF8&s=electronics&qid=1226809093&sr=8-1)
