i dont sling my guitar often, always sitted when im practicing, with the little leg rest u see ppl using when playing classical guitar. that gives me more access the higher frets.
ha, im not sure if it works for anyone as well, looks nerdy though.
i think it will have to depend on individuals height and arm's length.
i use to strap it damn low where my low E is at my thigh the humbuckers are below my balls hehe
but currently i'm at waist level.
i think it's best to always practise while standing, which is what i always do ever since i started guitar. It was just for the sake of fun in the first place to jump around while playing at home :lol:
