Looking for a new top tube bag, as latest frame has bosses what's anyone got and are they good, or should I just stick with my Velcro straps?
I’d use the bolts. I’ve got the Velcro Restrap on my Fairlight (no bosses), ahsat has the bolt on version on her Niner. The bolt version is neater and a better fit IMO. Quick to remove if needed
If you don't mind the price I'd recommend Apidura. I used one in heavy rain at the weekend and it stayed completely dry. It’s got a magnet closure that works really well one handed. In two other bags I’ve tried neither have been waterproof and both of then needed a bit of faffing to get the zip done up again with just one hand. I also like the shape of it as I can get a phone in it if I need to.

Cheers, for the suggestions, found the Specialized/Fjallraven one and bought it.
I've got a salsa one which is neat and tidy, understated and functional.
