TaosN--you have the correct ski: Rossi/Dynastar 65mm wide 182cm/25m. That is the best one for your height and weight. If you were 185lbs or more, I'd recommend the 185/27m length of the same ski. Likely the SPX15 binding.
Apologies, this is confusing to me, but I have more limited experience on race skis outside my own experience
and that of a very few folks in shops whom I ski with, and who also have an interest in skiing race skis.
To me, there are really different dynamics involved with different lengths and particular skis.
So what I'm experiencing may not fit others? Dunno.
Also, yesterday I just skied briefly with a junior youngster (of maybe 120 to 130 pounds, no more, I'm guessing),
whose coach had encouraged him in his choice to now switch to the 188/30 ski from a shorter junior GS race
ski, for racing rather than just recreation. Not sure if this will be premature or not, but this junior had tried some
188/30s, and loved them, found them easier, he said.
I'm only 5'10" and at this point, no more than 150 lbs. on my best day. But I prefer the 188/30 by a lot, and
prefer masters GS race skis that are 184 or 185, at least. (Not counting old timey skis, I've owned 180s,
182s and 183s, especially the old spec 183s, in addition to a 185 - and I've used a 187, briefly.)
What I experience is there is an "in between" (SL and GS) distinctly different feel/dynamic below 182 or so.
And another change at around 175.
For me, most ~175 near race or GS Jr. skis are too quick, edge to edge, to give time to really flex the ski from tip to tail:
instead, one dances from edge to edge easily and
very quickly (or overpowers the ski, if it is too flexy). Whether
one likes this quality or not, it is a distinctly different dynamic. (For smaller juniors, I understand that the experience
is different.)
Again, for an adult, at around 180, the GS like ski becomes a different feel again, for me, while still being fairly quick
from edge to edge: if it is not too soft-flexing, it carves/flexes in a way that allows working the ski more, but not to
the extent of having a GS ski feel (GS feel = partly, at least somewhat laid over, creating a roller coaster like rebound from
the flex). The 180 has some of the feel that Franz Klammer in retirement likes so much with his near race
iSpeed and eSpeed 180/18s.
At some point with a wider and or stiffer flexing GS like ski, maybe starting at 183 or 184, depending on the ski,
I get a flex that changes, that involves a real GS carving/rebound/flex feel, for want of a better term for it - with
more tip and tail involvement. Once this change in dynamics happens, the characteristic turns of GS become possible, likely.
For me, I get that effect maximized starting at around 184 up to 188 or so, seems like - again, depending on the ski.
This GS rebound effect/dynamic becomes too much, for me, and for presumably my size, past the 188/30.
For me, a 190 or 193 men's GS ski has clearly too much force, dangerous in the snap back rebound, and unwieldy.
