i've got a truball sabretooth. its nice, and works flawlessly and is very quiet. i'm hunting with a carter 2 special this year. just can't stomach the feel of a 4 finger anymore after shooting a 2 finger bt release all year. one advantage to a carter handheld is you can hang it from your loop and leave it there. it does make noise to cock it - and if you release it just sitting there - but when you shoot it it doesn't make a sound that i can make out.
