Hope an analysis of the gator board Harris and gator board Prospect will help describe things, at least on the continuous side and then you should automatically understand the two different 3-stage rockers.
here is a side view pic of each (one with harris above and the other with the prospect above for better comparisson). The harris is continuous. notice how the prospect looks a little like a "three-stage sitting next to the harris? This is because it has two different bends of continuous rocker in it
it bends shalower in the middle and then "abruptly" towards the ends, but it does this more fluidly, unlike my cheesy MS Paint pic above. Abrupt three-stage rockers atempt to give riders some of the advatages of 3-stage without sacrificing continuous rocker over all... or at least this is how i understand it from things i have read and looked at... i have never ridden one... just f.y.i. If i have explained this wrong, then i am sure someone else will come in and correct it ;)
NOW, i couldn't find a side pic of a 3 stage and abrupt 3 stage for the same company, but, how i understand it is that an abrupt 3 stage is like 3-stage on 'roids. it has even more of an abrupt kink in it
and to add another "hybrid" to the list is "PROGRESSIVE continuous" which is very similar to abrupt continuous. the bend gets progressively greater as it moves from the center to the tips... also atempting to mimic 3-stage somewhat.
Also, Murray's new '08 board has really taken "HYBRID" to a T. it IS a continuous board AND 3-stage in one, check it out too
AND i second Nate-O in trying out Slingshot. WAY WAY soft landings. if you have not tried one you gota do it. just so you know how you like it. To me, not trying a slingshot (i.e. responsive/rebounding flex board) is like never trying one of the two families of rocker. completely new flavor bro.
