The moose platform, one blade at each bolster, leaves you slightly more room for your index finger when the knife is open. Also it's not resting on the spring notch. I find it comfortable. That being said I carry a Big Jack platform, two blades on same bolster end, almost everyday. I don't notice the notch on this set up either. Both of my 54's are Northfields and have long pulls. I don't find the moose pull any different from the jack. The only thing I noticed is my moose seems more stiff from the half stop to open than my jack, but sometimes my jack is stiff to get out of the frame. If i noticed this it just needs a drop of mineral oil. Also I find that the lifter on a beer scout or a crown lifter fits great in the long pull to aid in extraction. The heft and stiffness of the 54 is comforting and of quality.
