I am shooting your identical setup except with beman shafts and my pro shop suggested 340"s so thats what I went with.

[sharkhunter]

Yep just went to 340's myself (74 lbs @ 28in). My groups are better, and BH flight is better as well...

340's out of my Z7 at 68lbs 28''dl (just lowered my weight to about 66lbs and the 340s
still shoot sweetly with a 100gr fp or bh...

Maybe even stiffer. Hard to be overspined with that rig.
