Just spent 2 hours trying to rig my new switch blade, but could not get the cams to pop on!!

Tried all the tricks from a previous link including removing the metal spacer, max outhaul, downhaul completely released, no battern tenson. Even then the cams are still tightly pressed against the outside of the luff.
Starting to think my mast might be to stiff if thats possible.
I am using a Hypersonic 55% 460 SDM.
