Hi dave, and welcome to the group!

There are a few folks on this forum who can best answer your question--pooldoc and Waste being two of them--and hopefully they'll be by soon to look at this thread. In the meantime, though, you can use the Google search feature linked in my sig to search for other posts around the forum, and you might find some helpful answers. I know in the past people have suggested bowling balls and other items to help smooth the wrinkles out.
