First off, I am not particularly an advocate of ultra high blades, I really don't care to argue any of the points, I was just trying to answer the question as to why some folks feel the way they do, and I haven't forgotten anything (well, that ain't exactly true cuz I am so damn tired of working 8 days a week here lately that I can't remember my own name half the time).
But do go out to the shop and see if you can't feel the difference between a high and low blade, particularly when first starting the cut.
All my life I have noticed the tendency of a board to "ride up" if the blade is low when ripping, and that tendency disappears with the blade set up high.
Hell, maybe I've just been dreaming that my touch with the saw has been good enough to "feel" that..
