Re: Brass vs Tungsten or both
Personally, I use almost all tungsten, but I also rarely use weight outside the flies themselves. I often use double-tung stoneflies and hare's ears with extra-large tungsten thoraxes as a heavy fly, paired with another lighter (but still tungsten-beaded) fly. My most common set-up lately has been a tunghead hare's ear with a frenchie dropper. For me, snags are sporadic fact of life in nymphing, but I'd rather be where the fish are and do so without needing to add extra weight.
Working out a way to convince my university to allow me to hold my TA office hours on the nearby creek...
