Re: Turning Over Popper Issues
8' of total leader length is about right for poppers, and making the butt long will help with turnover.
Adding at least a single haul on the forward cast to increase line speed should also help.
Per Frank's point on setting the hook at 50' with a soft rod: I think if you use anything but a strip set on bass you're asking for trouble. You're going to have a hard time applying more than 4# of hook set force with a rod sweep on a slow 6wt, but you can apply more force much quicker with a strip set.
Leave the rod pointed at the fish and make a forceful 1-1.5' strip while gripping the line tightly. Once you feel the fish struggling, then sweep the rod and begin bringing it in. If you don't feel a live critter, wait, and he may go after it again. Unlike the sweep set, you've only moved the fly 1' away, instead of 10'.
