I'm shooting them out of my A&H ACS bow, which is a radical hybrid longbow. I am shooting the Dangerous Game version because I got them on accident. They come in at 630 grs so I think I may have preferred the normal for bows under 60#. Anyhow the shafts are great. Very narrow diameter, incredibly tight tolerances, and they fly beautifully. I prefer them to straight carbons tremendously and I am starting to like them more than straight aluminum. The only downside is the cost, but you have to pay for the best. I'm still undecided on the hidden inserts but I have had no problems with them.
