the specs on Jameson’s site put the entire weight of the instrument at 9.5 lbs.(no tone ring) So it is very light.
The pictures on the site show place to hook the strap as above the heel.
This is a neck-heavy instrument.
using a leather strap with a rough inner side could help some…nylon and smooth leather can slide pretty easily.
Attaching above the heel would mostly help keep it form flipping over face-down…but not much effect on the neck weight
