you could set up some dummy lines to run some deep umbrellas...no rods or reels needed. just a strong back and some gloves to pull that sucker up!
two lines will definitely make it tough. i know guys pulling 20+ that are having a tough time right now. the bite has slowed while the bigguns are up in the rivers spawning...just less fish in the main stem right now.
your speed doesn't sound too bad. trolling east-west (or even quartering) rather than north-south will help you cover more depths. it's not a bad idea to start out at a specific depth, but the baits move around thoughout the day and with the tides...and of course the stripers follow them. i like to troll in to about 35' and then back out into the channel. take note of where your're marking baits. after several zig-zags you may notice a pattern and can then try to match your track to where you're marking them.
yeah...the flies were a pain. the lack of wind on saturday was both a blessing and a curse!
good luck...and remember, there's plenty worse ways to spend a saturday than not catching.
