So this got me thinking, maybe at 193 I'm not heavy enough to easily handle the 176 tt80? ...
Racing technical skis, even the WC versions, which you aren't referring to, are not what mythology makes them, I-beams. Specifically, they are designed to be incredibly stiff side to side, to resist torsion. And typically the tips and tails are very stiff, to make the ski handle ruts and rough snow smoothly at speed, as well as create a good platform in the tail for acceleration into the next turn. But in mid-ski they may actually be as flexy, or more so, than a "stiff" consumer ski. This allows them to bend deeply and quickly into the apex of a turn. Much of what we call "grip," in fact, is achieved by damping, weight (racing skis tend to be heavy by design), and torsional integrity so that the ski will remain in contact with the snow at all times. Longitudinal stiffness is more associated with stability at speed and lower edge angles. Thus, as you look toward faster events with less turns, the skis get longer and stiffer longitudinally. Sl's can be fairly easy to bend in mid-ski, GS's less so, SG's and up are real planks.
Which is my typically long winded way of saying, no it's not your weight that makes you have issues with a recreational carver. In fact, the opposite is more likely; you're too heavy for a 176, need to get a longer ski. Also you may want to check you you are/aren't keeping your hips forward and pressuring the tips. But yeah, GS's can feel like they do all the work for you, until you have to turn in predetermined space. Then the fun begins.
