Still getting used of it but it is simple to use and comfortable.
The Avalon finger sling on paper is a good idea. However the plastic tighteners are to loose to hold firmly on your fingers. I fixed this by putting a rubber band on each side which worked. But really the whole system is unnecessary. Almost all archers prefer making their own such as what I did, it performed better and is customizable (Also free!). After using both I realized fast that I could get a smoother bow swing when using a custom one. Don't bother with this, just tie your own using a shoe lace.
I got all the sizes only ended up needed the small but they were cheap enough and tryed to put in enough to get free shipping
The sling is comfortable, but does not fit very securely. The rubber adjusters are just not up to the task. However wrapping some string down the middle made it tight enough for use.
One of those accessories that seems a small detail but is integral to your shot. This sling is easy to adjust and comfortable on the fingers. In time, though, the seam can break down and fail under repeated use, so it’s a good idea to order a spare.
