I'm thinking of buying a U1 SDR on the bracelet, but I really like the look of it on the Sinn rubber also and would love to have that as an option.
However, the Sinn rubber strap is substantially overpriced (outside of Germany anyway), and is also silicone rubber. I've not had good experiences with silicone straps - they pick up fluff/dust, and they go polished/shiny if I wear them under a sleeve. Overall I just don't see the value in buying a Sinn rubber strap for potentially occasional use.
I've been looking at the Bonetto 317 or even the 300 as they are pretty good quality, are very affordable, and come in red and black (I could buy both colours for less than the cost of a Sinn replacement rubber part without the clasp even).
My question is, is anybody rocking the U1 on a rubber strap that's not Sinn?
For reference, Bonetto 317:
