Welcome Andy! If it helps any, I've been casting for decades and feel like I don't know anything at times either.
Please ask our merry band of enablers any questions you want. The more we help others learn, the more we learn ourselves. And there's no such thing as a dumb question if you really need the information. Watch for thread drift! We take a lot of side trips to get to our destinations, and it's a lot of fun! Sometimes the drift is more interesting than the original topic. Enjoy!
