@maceww6438 I agree with @Michael_Mark . I started with an A style and attached it at the headstock and became use to that position. when i purchased my first F-style, I couldn’t wait to put it around the scroll and look cool like all my favorite players, but my headstock would fall every time. And i didnt realize how much I rest the weight of my thumb and playing hand on the neck until I put it around the scroll. because my hand position was pushing the headstock down. I was also using a simple paracord as a strap, which is slippery on a shirt. so I guess a person could fix this with a leather or my “grippy” strap, But in the end I left it around the scroll and altered my playing position slightly to adapt to the new weight distribution of the new strap placement. When my strap is attached to the neck i can play with the mandolin in a position that is further back on my side, slightly under where my arm naturally hangs, think of how a guitar might be held. But when I put the strap on the scroll, I have to move the resting position of the mandolin further up and more center of my body, so that my arm and stomach create a sort of “nook” for the mandolin to rest in (or my knee), keeping the neck in a position I like and bearing the weight of my hand hanging of it like a monkey bar.
I think it comes down to how you are comfortable playing. I think how some people play with their mandolin neck almost completely horizontal and others at an angle. I have seen some where they keep it almost up to their chest while others, think Sam Bush, have that thing slung lower than a bass player in a punk band, haha. So i would say experiment with it, and as long as your technique is good, go with it.
