I recently picked up some X from Chad. Made my first string with it last week. It does seem quieter than the D97 that was on the bow (Hill Halfbreed). That bow was pretty darn quiet to begin with, but there was a noticeable "twang" without silencers. That "twang" is now just a short, low, buzz at most (also without silencers). I went with Chad's recommendations and built it with 18 strands, loops padded to 24 with B50 and served with 0.19 Halo. Fits my X-nocks and Bearpaw 5/16 indexed nocks (on tapered Surewoods) perfectly. Just a light, audible "snap", but still moves freely up and down the serving.
