Bull Gills on Bro's Frabill straightline 371 rod and reel

We are having a blast catching big gills on this incredible rod and reel combo.  This past Monday we had fish flying up off the bottom almost the entire time we were out.  The biggest gills we caught were pushing 10".  All fish were released back.  We've been loving the new VMC Tungsten Fly Jig.  Many of the fish we caught were hooked on a jig without bait.  These jigs are heavy and fish love them.  Not sure what turns these fish on with these jigs, but I wonder if the slower fall rate triggers the bite.  The hackle also adds something very life like to the jig.  I'm not sure what it is, but if you haven't tried these yet - you've got to do it!  If you try them, let us know what you think!
