I'm thinking about getting a flex king liner for my insert.I know the pro king is smoother on the inside.I was wondering if one was easier to work with than the other?Im looking at a 4by 25ft.
I didn't go with the pro just a flex king. seems like it'll work just fine.the single ply was easy to manipulate and cut.I got the insert up and running and I'm very excited not to use oil to heat my house.
