All, thanks to all the info so kindly posted here as well as tons of research and most importantly the awesome lecture by the Saba Slayer!
Went the other night to the big bay to a spot I had previously scouted anddropped my nets at sunset and was home by 11pm had three shorts and a half dozen flapjack sized round rays as well as a trio that decided to follow me home........
Had to teach them a new trick as well....play dead on the dinner plate!
Thanks for viewing and most of thanksfor the awesome site and great people here with the info.
