Yep, I have a PCH II 58" 58@28. My current arrows are Arrow Dynamics HammerHead Trads with 200gr up front. My draw is 28.5" and I have them cut 29 1/4" BOP. The AD Trads are the stiffer spined AD's. I never could get Beeman ICS Bowhunter 400's to fly right, so when I went to order new arrows, I went with the AD's. I liked the idea/concept of the tapered shaft and the ability to fly well out of several different bows. I still want a set of FMJ's and if I do, I'll go with 340. I too, think Widows like a stiffer spine. Good luck.
