Barry-
I also bought the UFC BX model; UFC BX & the UFC 173N(alpine), were matched to my depressing over weight body. The 163 UFC was not, he had one laying around. I am trying to make the trip to SES, just not sure if it is going to happen. If you have any other questions, please ask. The FLP will be the first of many Virus's for you, just a hunch.
