One reason I use SMAs is so that I can use the same patch leads for both my HF and VHF gear. They also link easily with MCX (via an adaptor) so I can plug the Sark 110 in without yet another patch lead. But they are certainly not the best in cold weather. I like the idea of SMBs, might give them a go.
