Per usual the savvy Britons over on trek-lite.com were the first to be on top of this latest development.
Brilliant on Henry’s part to offer both fly options, TT’s IG page mentions 30D silnylon being a better choice for “higher elevations or shoulder season”. The Notch comes in a stealthier green color now as well. 20D silpoly fly weighs about 0.7 oz less. Sales will go up I’m sure.
