Dell's had my computer since Monday and I just got it back today.
All the flies I posted can be fished with a 6 wgt. The pencil poppers and the last one are the ones I would most likely use with a 6 wgt. I can cast the others but it wouldn't be as much fun, more like work.
I can't see that far back on the string, but someone mentioned tossing an 8 inch fly with a 6 wgt. I fish 5 to 8 inch flies when I go up to Ontario for my vacation with my 6 wgt and have been able to handle pike up to 28 inches on it. I think it's a misconception that large flies have to be heavy flies. It's not that difficult to tie a large fly that won't knock you out if it hits you on the back of the head.
Transfer foil. I use to find some in the local craft stores but not anymore, not sure why the don't carry it around here as it appears to be a staple in the arts and craft world, but they don't. Now, I either pick it up at shows or on line. Google "Jones Tones"
I'm pretty sure they're set up for on line sales now. I use mainly Mother of Pearl or a couple of different holographic silvers and holographic gold on occasion. If you've seen "loco foam" or "sili skin" then you've seen transfer foil after its been applied to a surface. For sheets of foam, you can either use the adhesive backed sheets or coat a sheet with foiling glue which dries translucent and tacky. For popper bodies you apply foiling glue to the bodies and when it's tacky you apply the transfer foil dull side down, pull the backing off and the foil stays on the foam.
