Rod Flotation ?

Was going to make rod flotation from pipe insulation and found there are two different thicknesses of 1/2" pipe insulation . One is 3/8' thick and the other is 3/4 thick , what are you fishermen / women using ? Thanks , Dan   

I use a small section of pool noodle. Slit it length wise to the middle. Slip it over the rod in front of the reel and secure it with a velcro strap. Just make sure it doesn't interfere with your reel or line.
It is easily interchangeable. This way I can use them on only the rods I take with me.

I use 3/4" pipe insulation for added buoyancy. If the 3/4" insulation interferes with your line, then use 3/8". Make sure the length of insulation you use will float your rod, reel, and heaviest jig you use. I tested mine in a swimming pool.

Pool noodle.  Sliced like above.  I leave mine unstraped and remove while fishing with the rod.  Easy on/off but they stay on when I toss my rod in the water to test.

It depends on how much floatation you need.  Some setups weigh more than others.  On most of my gear I just used the 3/8 thick insulation for 1/2 in. dia. pipe.  I cut it to be a little shorter than the distance from the front of the handle to the first eye and attached it with zip ties or black duct tape.  Easy to put on, easy to remove.  I tested it by tying on the heaviest jig I though I might use and then tossed it in the water. 

On one of my rockfish rigs, I used a pool noodle.  It sometimes gets in the way of the line.  I even tried trimming it, but it still hangs up on it sometimes. 

You should test it with the biggest diamond jig you expect to use too...

I use leashes, those work even with a 20lb ling on the end. 

Don't drop your rod in the water. Problem solved.   
I filled the handle of my net w/pool noodle though.

I used to use leashes until I watched MontanaN8V get all wrapped up in his.  I also managed to do the same myself once.  It's a pain in the rear getting yourself untangled from your leashes at the same time as trying to climb back on your yak.
