I guess was revived! We had a lot more to say on the topic
Well, update on the OP - I play two Lull M4Vs these days - 8.0 lbs and 7 lbs 10z. I'm happy as a clam and I don't get shoulder issues even for long sets!
Cool. After years of flipping basses I have settled on a Lull M5 as my main player and have played virtually nothing else since I got it about 8 months ago. It weighs
7.8 lbs

At this point I own 5 basses (all 5 strings), and the heaviest one is under 8.5 lbs. The lightest one is a 5 lb Basslab Soul, and it sounds huge.
