I think you and I have had this conversation before. Again, I get it, but let's face it, if 7.5 lbs. is your mark, you would not even consider 99.9% of unchambered L.P.'s anyway. So again, a non-issue. I'm not kidding when I say I have had probably a dozen people that just HAVE to know the weight of various L.P.'s I've had up. I've told them no problem. If it's a done deal except for the weight, I'll go do it for you. What's your cutoff point? Of the dozen, only ONE person responded back. The rest dropped off of the face of the earth. The one that responded flat out said that he wasn't going to necessarily pull the trigger, but wanted to know. YMMV, but that's been my experience. I'm too busy for trivia questions.
