I can now report with complete confidence that carp WILL eat a #6 unweighted brown wooly bugger. No bait or scent required! On one day I had two followers and then a taker that promptly snapped my leader and swam off with my only brown bugger. I tied up a few more that night, and the next day I tried them at another lake where I eventually hooked and landed a nice 8 - 10 pound mirror carp that took me right down to the backing on my 9 wt!
