I've never used one. Found a 50+ floating today still attached to the jug. What a HUGE waste. Ya'll make sure you check them often (every couple hours) in this warm summer water.
i have this roll of thick white tape like duct tape, but i put a piece big enough to write my info with a sharpie so it doesn't erase and i use an erasable marker for writing the date. that way i can just rub it right off....
I bought my noodles from http://www.fishingnoodle.com/WHITE-FOAM_c3.htm. Only problem is they have a 3/4" id. So I had to make washers out of some thick plastic laying around to go between the cap and noodle.
I write my name and address on the tube and the date on the cap with a sharpie. Wipe date off using acetone. Saw in the new regs where your date is only good for 10 days instead of 30, so watch out.
