Mike from Texas...I shoot a Scott Mongoose,but,I tried out the 3-D Thumb Pull from T.R.U.Ball.Very nice release,but I' am used to a wrist strap.So,I found a wrist strap for the Tru-balls,it' s called a Jackie-Strap.It' s made to fit all the new Tru-balls.Got it at Lancaster Archery in PA.for about 30.00 bucks,and they have a web site.Hope this helps.By the way,I' m still shooting the Mongoose,old habits are hard to break...Bob
