Yes, I do. My personal experience has led me to a policy of less is more when structure is concerned. It's not the right thing for everyone, but it is for me. I prefer PVC structure that is snagless, mobile, and will outlast me and my kids. I only have 5 concentrated areas in my 4 acre pond with this structure, but I also have tons of American and Horned pondweed that more than suffices for structure.
Again, my goals are to encourage predation of my BG, so less cover is what I want. 2:1 slopes and am now allowing my pond to drop about 4' this Fall to encourage more BG predation as they'll run out of aquatic vegetation to use as structure/cover/habitat.
Every pond is different - but this is my strategy to help
me achieve my specific pond management goals.
