Thank you all for your help. The black and silver [graphite/gunmetal] feather frame small has arrived. Fits like a glove and the colour scheme met with approval. It has not been tested on the lake yet. One slight moan is that Radar simply cannot get their distribution sorted out on this side of the pond. A delay in delivery, and now it has arrived with the mounting screws loose in the box - only 3 match and another random screw is included. Three washers, one of which previously has been used. Given that it cost £159 [not US$ but GB£] one might have expected the appropriate screws to be included. As I have said on other posts, my Radar Vapor Boa and HRT are great. It was just a shame I had to wait so many weeks for the HRT to arrive, despite assurances to the contrary. Anyway, it is more important to be on the water ...
