I'll try to keep it brief. I'm a 200 lb greenhorn and have progressed from the 67" Theory, to the 67" Senate C (MPD based), to the 68" Strada this summer. No brainer, Strada all the way (skiing at 30mph and 32 mph). It is much less work for me than the Senate C at the same speeds (why?) and I am far more consistent on the Strada. If I can ski the Strada at 200 lbs and 30 mph I can't image 28 being an issue for a lighter skier.
