I've been messing around with body stretch materials lately. While I was curing the fly I noticed how the wool yarn popped with UV. Anybody have an opinion whether trout care about UV? #killerbug#trout
They see it, we don't. Their eye structure is different than ours and allows vision in the wavelengths we can't see. Not really sure if any studies show that UV materials are more attractive but I use them in a lot of patterns just in case.
