Loader fulcrums

I have both my loaders set in the "height" fulcrum position, the ones allowing the loader to reach higher.
One of the reasons for recently purchasing my M9540 was to have another tractor/loader to pick up (2) ~850lb round bales with a dual bale spear attachment. I finally got to try it out last week and in the "height" position, it didn't want much more. Dual bale spear is probably about 400lbs, so total load is like 2,100lbs.
My question is, has anyone seen a noticeable increase in lifting power when switching to the "power" fulcrum position?
