I am looking at possibly purchasing 2 Sportsman series power poles. I was told that they're cheaper made and will not hold a fiberglass boat as good as the next series up. I have a 1991 boat so I'm not going to invest a lot and I could care less what they look like. As long as they hold me in position. Does anyone have these on a fiberglass boat? My boat is a 295 Stratos so it's 19 and a half foot long
