I love the BLR platform. For whatever reason, it seems that most folks associate lever operation with a 'carbine.' That draws them to the short actions. Personally, while I do appreciate the compactness and quick-handling of the short actions at times, I don't find it particularly different or more useful than a 'full-size' rifle for most of what I do. The BLR is still very quick and handy even in long-action chamberings (never handled a magnum-length BLR, though); quicker to operate than a bolt gun by quite a ways, IMO/E.
They're also super-strong of lock-up in their current form (lock up almost exactly like an AR), and the take-down models are super-cool.
