I like the material and they will hold fish. I've kicked around the idea of bumming some of this stuff and doing my own, along with some other stuff I do, and these were my ideas. Cut a 12" section of the pipe as a center or core to tie as many others around as will fit. PVC up to as big as the bucket will allow would work best. Drill 1/4" hole and wire them together as a cluster and then set it concrete after drilling 1/2 or 3/4" holes in the bottom of the pipe so the concrete will have a bite on the pipe. Drop these where they would be slightly overlapping and a wood brushpile at either end and it should turn on and be snag free except at the ends where the wood is. Oak will last a long time, and I mean limbs tied together and a concrete block or 2 WIRED on to them. Wave action wiggling the brush will wear thru the rope at the block and you'll lose the pile, I've lost 2. I have some out that hold fish pretty good. I also put branches in a 5gal bucket standing them up about 8' or more and then plastic stake buckets around that. Easier to find the wood part with basic electronics like I have, and once marking the wood, fish the snag proof stuff all around it. create a line from 8' with the bundle of wood to 15 or 20' with the other and it should be active all year. Have fun and good luck.
