I think that all LP's are heavy. Not many people seem to use Classics anymore, they all seem to use Standards or Studios. So there's the individualness too. The tapered neck is very playable and comfortable. It makes playing fast solo's at the bridge end easier, coz the strings are far apart so you don't accidentally catch another. N the nut end, it makes those hard to make chords a little easier coz its more narrow, so your not stretching too much. I've also had a little switch problem too, so make sure its ok before buyin one.
I think the finishing on the Studios are slighty lacking as well, they have a cheap look to them(just my opinion), n the Classic does have better pups. The hardwares different too, Classic has nickel, Studio has chrome, not sure if they make a difference.
As for buyin another make LP, it's not a LP if Gibson doesnt make it.
But at the end of the day, what I like you might not, so go try them both out n get the one your most impressed with.
