We often read that Strat players can't get comfortable with a Les Paul type guitar. They'd like to have one for its particular tone, but can't seem to bond with the heavy weight and/or its boxy shape. Funnily, they will like a Telecaster which is pretty close to a LP as ergonomics go. There are elegant solutions to this dilemna in the not so expensive guitar world. I went this way. If you need to buy new, you're in luck as Epiphone with its new 2020 line, came out with the Les Paul Muse. It has a thin body with a contoured back (belly cut). It is also chambered so the weight is around 3.4 kilos (7.5 lbs). https://www.epiphone.com/Guitar/EPIAU946/Les-Paul-Muse/Smoked-Almond-Metallic If you're OK with used, the Epiphone LP Ultra is what you want. They made the Ultra, Ultra II and Ultra III. They all have a heavily chambered body that brings the weight down to ±3 kilos (6.5 lbs). They also sport a generous belly cut. The first one they produced is just as a regular LP electronically, two Alnico Plus humbuckers, nothing fancy. The belly cut on this image was probably a prototype, as the real thing is more like the LP Muse above. https://www.musicradar.com/reviews/guitars/epiphone-les-paul-ultra-25064 The Ultra II introduced the Nanomag, a magnetic pickup integrated to the fretboard at the last fret, that gives the LP a realistic acoustic guitar tone. Pretty cool. It has two output jacks so it can be used in stereo. The Ultra III came improved with a pickup ring tuner, Probucker pickups and USB port. Still in the used dept, there's the PRS SE Single Cut that is similar in weight and carved back. It's available with humbuckers or under the Soapbar I name, with P90. Weight is again real light, under 3 kilos (6.5 lbs). This guitar you love or you hate, there's no middle ground. But if you love, it gives back a lot. I am sure there are others, but this is to show that there's more than meet the eye when LP shapes are concerned.
