Default Canopy compression struts

I’m sure this has been asked before but what compression psi should the canopy struts have. I know they’re 16” long but when I went to replace them O’Reilly’s air parts had two different strengths 78 and 115 psi. Those seem high but my old ones that have failed and only demonstrate 21.5 lbs compression strength. Canopy will not stay open.

I don’t want too much compression psi in fear of the canopy opening on its own when not secured. In Oklahoma you really need as much air as possible when taxiing on the ground during the summer.

I the second owner.

I replaced the struts in my RV6 a year ago with these:

I am running with 150N (~34 Ft.Lbs.) on my 7. Canopy stays open when starting/taxiing to beat the Texas heat...

Ditto on the Suspa C16-08941.
A bit stronger than stock, but not strong enough to twist the canopy around while operating.
Does well when parked on the ramp with winds head on.
