I totally agree with you on the swivel. I still have my Torque 1 bars from 2017 and that swivel works so much better. The swivel on the QR of the first Torque2 version which was an own Naish development was also super smooth. Unfortunately they had to withdrew it.
The current QR is an OEM product (same as on the Ocean Rodeo bar).
The feature which for me is key on the Naish Bars is their small diameter of the bar. Generally and especially in winter when I have to use gloves. For my taste it could be even smaller like on the Reedin Bar.
I think auto rotation should be a must for the next generation of the bar.
They should split the front lines like 6m + 16m + 2m extensions. A couple of bars have that and I do it with custom lines. Much more economical to replace the lower 6m which have all the wear from rotations.
Spliced loops on the line ends plus robust pigtails.
