I would buy the Gotama.  I found last years, this fall new, but I think that they are pretty much impossible to come by at this point.  Apparently al's ski barn bought all of the Gotamas from last year that were left over, and I got the last pair of 183's that they had.  I have only skied them a couple times, but am super happy.  Definitly my favorite skis i have skied.  The new Gotamas also have a little more side cut which would be better for you when you are on the groomers.
