I just went through with this process myself.
Samson is my choice if I have not gone with FW SS arch and go with an aftermarket Arch. They are aluminum (Brushed) 2 ½” diameter which is little bigger than FW polished Stainless Steel arch. I have not see the real one myself but after talking to Samson I did get a great feeling about they are great quality product.
I have pulled a trigger on ordering a FW SS arch with new integrated Bimini. FW`s latest Bimini for SS arch is much bigger than anything out there for arch application and I felt they are worth of investment. Unlike older Arch/ Bimini package which had separate forward lean Bimini the new integrated Arch/Bimini is much sleeker looking... Unfortunately the retail cost for FW. Arch is $6377.00 but it is with new Bimini.(6 hours of installation is required as well) They are still not cheap but they are polished Stainless Steel and very high quality. We are sacrificing having a camper canvas for now so getting a large Bimini was a decision making point.
I have looked many others including ones can fit existing Bimini (Arch will look too high on the boat) but we felt they all are not as clean as Original FW Arch. The arch for my boat should be ready by mid June so I will post picture as soon as they finish. In the mean time take a look at these close up FW Arch with Bimini.
