the lightest r9 i´ve played was 7.8 lbs and it sounded like a dull strat. really awful...
the heaviest lp supposed to be ca 11 lbs but it felt like 20 lbs. it was a early 80s lp. the pickups were junk and the guitar sounded very steril and compressed.
my fav weight is everything between 8.5 and 9.2 lbs.
FWIW, my '13 R9 weighs 8.6
Contrast that with my '81 LPC that is a backbreaking 12.4
Are you kidding?
I just sold an R8 that was around 9lbs 13oz because it was killing my back. I totally loved that guitar, but it was just too heavy. Replaced it with an R8 that is 8lbs 7oz. Strange as it sounds, it makes a huge difference. That range, right around 9lbs is where a half pound heavier or lighter really makes a difference.
