The 13xx spring is stronger than the 22xx spring but weaker than the Disco spring.
22xx -> 13xx -> Disco

IIRC, 22XX valve are 9/16" NF and 13XX valves are 7/16" NF.... too lazy to go to the shop and measure tonight.... *LOL*....
Spring rate.... Disco > 2200 > 13XX > 22XX....

I am also thinking about cutting the nose off of a 760 nose and using a tap to turn it into a .6" 13xx valve extension to get about a .2 ci valve for a 66/13xx... a lot of pumps but maybe enouh to get a .25 pellet past 700 fps.
I just need to figure out how to get the .54 id oring seat area and if I could just use a #54 drill bit.
Will have to wait till the Mk177 gets here to see what is possible with it and see if you can extend the valve...
