I needed a Bimini that would work with the factory forward arch tower, since I didn't want to pay 1300 for the factory Bimini. I found a large under tower Bimini that works perfect for about 450. The only thing you have to do is mount it backwards for it to work on the tower, back goes to the front.. I would have flipped the brackets, but they are assembled on the tubing and captured by pop rivets and didn't want to drill them out.. Seller is on ebay.
