Another vote for Smith...I use the Factor Max with interchangeable Lenses (Grey,Copper, Amber & Clear)..I like to change out to Copper on those really grey/flat skies ...The grey works great in High Sun..And the amber adds another 15 minutes visibility to the evening or in really dark skies...3 seasons and no complaints...Prior to those, I had another interchangeable lense model from H3O which I bought at the show...I liked them alot but I got too close to a customers backcast and they ended up in the drink...
