Line weight is governed by the size of fly you want to cast --
for panfish, probably #16 as the smallest dry fly to size #2 streamers.

I think you could successfully fish a long time for bluegill without ever
going above a size 10 popper. Personally, I'd go closer to a 3-wt than a 6
wt. Perhaps 4wt would be the best compromise. There are some situations
that might be unfishable with a 3-wt, but you'll have a nicer time the 80%
of the time you can fish with it.
