I've used the T/D sleeve you can get from several suppliers and the bow bolt from Craig Warren. My favorite is the bow bolt, but it does have a degree of difficulity to install. I've broken 4 bows I installed the bolt in so it's not for the faint of heart! When it works it is the slickest, cleanest, and least obtrusive system I've ever seen. I have one in a 66" 61# longbow I took to Africa and I've put thousands of arrows through it, it's my favorite bow still today.
The sleeve works & is much eaiser to install but you have to use a handle wrap and I've seen them shoot loose. what I mean is that I've seen them have a little "tick" to them on the first shoot after putting the bow together through the years.
