Thanks all for helping me decide! I ended up pulling the trigger on the R99's since I've had the tab open for the past 2 months and love the thinking behind the skis.
I'm certain the M102, MF108, R9, and the B97 would be great options too! My thought process was if the R99 isn't what I'm looking for it will be easier and quicker to catch and release the R99 here to pivot to one of these other options than it would be to go the other direction. Hope to do some laps with you all up at Alpental/Crystal next winter!
