Hi im new to the forum and was looking for advice. I have been flyfishing for a year now and havn't done anything put nymphing in rivers. I just got my 11 year old set up to fish with me and wanted to start him tubing. A local I talked to told me to use sinking line and not sink tip, but reading flyfishing 101 on this site says to use sink tip. Could you guys that are good at this tell me what line or lines I need for us? We both use 5 wt. rods if that matters, Thank you.
