Yeah, trying to decide between the 176 and 184 cm FX84's is a really tough call without demoing. But it's impossible to find the Kastle lines to demo in Seattle area, closest is down in the Portland area. Had a chance to try the 178 cm MX88 last week in CO, but the conditions would not have been fair - mostly solid crust and ice. Also, I didn't want to chance the demos on the multitude of exposed rocks on the slopes there.
If I stick to ≤ 40% powder, the finder lists the FX84 as a viable choice (In reality I probably ski more heavy off-piste snow/powder/crud in the PNW at Crystal than that 40% might indicate). Like you Kauffee, I seem to be in between the 176 and 184 with the intermediate setting giving me the former and the expert the latter. It doesn't seem to make a difference if I set my weight from my body weight 180 lbs up to at least 200 lbs ( all geared up?), with the intermediate always giving me 176.
It's a tough call without testing.
Anyone else out there with experience on the FX84 sizing?
(Oh, I should also add that I also have a pair of 183 cm iM82's which is a nice damp ski for soft snow and crud but isn't as quick as my old Legends. If I buy and really like the FX84's, I could also maybe mount them up for some backcountry stuff).
