Well I use cheater glasses for putting the fly on the line but like you...I can't see the bloody thing on the water anymore either and I'm still too stubborn to get the bifocals. I don't see THAT bad yet. I put a LITTLE piece of float putty on the tippet knot or about 18 inches from the fly. Anytime I see a rise anywhere near that close to the putty, I lift the rod. Otherwise I tie in a bit of bright yarn or fur into the fly if I can.
I like this new format...I can make the print big enough to read!
