Funny, soon after posting my reply we went out fishing and I caught a number of hybrids that I think may be RESxGSF. They look different than my regular CNBGxGSF hybrids which I also have quite a number of. The CNBGxGSF all came out of my sediment pond where I stocked CNBG and RES.
Pictures of the candidates below. Last picture is of a pure GSF for comparison.
