Greenside Bunker Play

[O.B.Left]

not sure I understand your grip but if its working go with it. sand shots are different animals .. what creates compression off of turf is ill suited for a sand shot which is more.... as you say scoopy or throwawayish or at the very least cross line . Me personally I think much can be done at address, cross line open face , exposed flange swing as per normal. But the best in the world also vertical hinge a further sophistication or whatever. Shot at hand depending. No shaft lean is important too.
