I think it's cool that they added a new loader and some corresponding changes to make the regular L lift a lot more weight. It's at the end of the video. They also have lots of BX changes coming as well.
Doesn't matter what they do to the BX, it'll never be remotely as capable as an LX. An LX is two sizes up. If you have space for an LX, I wouldn't trade to a newer BX, I'd get an LX.The supreme BX looks interesting. Need to know more specs. Been considering a LX2620 upgrade but will wait until I know more. Lift capacity is my main concern.
