Post', if you search Pow Wow you'll see this question has at least a dozen threads. That being said, currently, it's apples and oranges, I've owned enough of either system to share my opinion that one isn't necessarily better than the other, they're just two solutions to the same problem. The bottom line is there needs to be a competent bowyer building either system. Personally, I gravitate toward the Bow-bolt for the bit of extra mass it adds to what would be an otherwise lightweight one-piece bow...the sleeve system (unless it's the old school brass/steel one) adds nothing to the bow mass, so on bows like that I prefer as heavy of a riser wood as I can get, otherwise you still have a featherlight 1pc bow. My last sleeve bow had a Leadwood riser from Big Jim and it was brilliant with just the perfect heft. Both systems are quick to break down for storage. The Bow-bolt has threads obviously that need to be protected from abuse, but the sleeve has its own niggles...like occasionally if not properly maintained it may be difficult to pull apart. I have also owned one sleeve bow from a well known bowyer where the fit loosened up after about a year or so and you could feel a very small amount of flex on the draw/release because of it. This was a total oddball and honestly the bow still shot just fine, unfortunately I was not the original owner so I didn't pursue a warranty claim or anything like that. I only mention this because some folks criticize the Bow-bolt because back when it first came out some folks were retrofitting wood riser bows with poor results and so they cheerlead for the sleeve claiming it's faultless. The Bow-bolt if built properly from the ground up with a riser incorporating Micarta/G10 is a great system. Another difference is the sleeve makes the 2pc nature of the bow invisible whereas the Bow-bolt you'll still have a thin seam in the middle of the riser. On any Bow-bolt bow I've owned this is never an issue holding the grip, you can't feel it. In the end, pick the bow from the bowyer you want. I wouldn't choose a bow based simply on what system it used.
