[Cimbian]

Left-handed recurve archer - very consistent form and release etc.
Hoyt Helix
34lb CRX to make a 68" bow
TS-Plus string 20 strand
27" AMO D/L
ACC 3L-04, 26.57" raw shaft length, 27" AMO arrow lenght
Easton 100gn parabolic point
Beiter insert nock #1 3L-04 Uni-Bush

Arrows spine okay on Easton - online chart.
Also spine okay on Archer's Advantage (slightly weak if anything).

After a tuning session a couple of days ago when all was well I re-fletched his arrows using exactly the same type (FlexFletch low-profile), same fletching jig and same offset angle (none). Now the arrows are coming up very stiff.

Bow setup is as before but double-checked anyway.

Checked clearance with foot-spray, all is fine.

Increased poundage and arrows coming in but I'm now at the max for the bow.

Backed-off pressure button to the point where it is doing almost nothing and the arrows are almost there now on a paper test at three different distances (approx 2m delta).

I just cannot see what is wrong unless the button is bottoming or jamming but it feels free and okay (though way too light).

Any thoughts, anyone?
