The CSI is a more sophisticated steel design compared to your 760 and P-mount.

With the Colorado Concept tubing, the down tube and the seat tube flare in size toward the BB. This seems to stiffen the BB and helps turn torsional forces into forward motion. On my Legend Ti, the "plantedness" of the rear triangle is the first thing I noticed compared to other designs that lack the Colorado Concept tubing.

So if you really like stomping on the pedals and like the geo, yeah, go for it.
