Any tips for remmoving a stuck Summit 2 valve top?

The main bladder on my Prowler is finally speeding up it's slow leak enough so I want to replace the bladder. I had no issues replacing the bladder for the floor/seat, but getting off the threaded top cap to the Summit 2 valve for the main tube is giving me fits. I just can't get it to unscrew. The "official" summit 2 wrench just does not provided enough leverage to get it freed.
I don't want to over torque it for fear of breaking the plastic fins...

Has anyone found a way to get one of these un-stuck?

TIA,

The outcast/aire support folks got back to be in less than an hour. The simple solution is to inflate the boat. You then have plenty of rigidity to work against.

They sure do support their product!
