I had them made. The work was about £100 the bits were about £100 I think, it was a while ago now. Sorry I cant put any pics at the moment up as the poles are where I store the gear and im at home, but I will put some up when I can. If I was gona do it all again though and I knew about the sl2 base sections I think I would have used them. (but upside down so the lips not a problem)
