My initial thought was you should be too stiff but the shaft length had me guessing. Ran your set up in Stu Millers calc, sure enough, too weak.
I shortened the shaft to 30" and swapped the 100gr insert for 50gr and got 465 total arrow weight, 10.2gpp, 15.9% FOC, 184 fps. Spine is within...
I have an older PSE Spyder that was my wife’s. She’s no longer interested so it may as well go. Probably have arrows and maybe a release to go with it.
