i have a H22 and a PT57A both with open pattern. The H22 center 8 main strings are very tight while the outer strings are very open from the visual check, Wilson saved 2 main strings from the outer area obviously. the PT57A 16*19 mains looks much better than that, but the crosses are much tighter than H22.
just hit the H22 with the champion choice once(47/45), the first impression was a little stiffer than PT57A, but not very sure on that because the PT57A was strung with poly/syn gut and tension was very low(low 40s), i will strung PT57A with the same string & tension and see the difference. The other difference was the H22 sweet point is smaller(potential reason may be different customization or string distribution)
