I was watching this combo for $70. The seller sent me an offer for $60 for both strap & clamp, so I took it. All of my attachments are currently thru AS clamps, but I'm certainly willing to broaden my horizons. I'll soon see how good Leofoto's manufacturing abilities are. If they are as good as I hope, I may replace my Manfrotto 410 geared head with their G4 head. It looks very promising.
