Love this thread as I'm a LP junkie!
The only advice I would give is find a tech in your area that knows what they are doing. Have a 1986 LP standard will all original hardware and I play it daily. The guy I take my guitar to has this setup perfectly. I bend a lot in my playing and occasionally I do have to tune a bit but no issues in general.
Have a Charvel from the 80's, with Kahler that would go completely out of tune once I used the tremelo. Everyone told me F Kahler.... get a Floyd Rose. I was so frustrated with the guitar I let it sit and never played it for years. A few years ago I stumbled across a video on youtube of a kid playing his Charvel and how no matter what he did with the tremelo it never went out of tune.
I took the Charvel to a tech that specializes in Kahlers and now I can dive bomb, hammer away and pull back without breaking a string or going out of tune, and now love playing that guitar.
My point is, find someone that know what they are doing to get you setup properly for your style of playing. It's all about the setup and fine tuning.
