cydwhitYeah, you are big enough you should be on the 190.
I've spent time on both, and I absolutely LOVE the flex patern on the 184, maybe my favorite flex pattern/shape combo I've been on in a hot minute, but it's just too short to be a super capable "all mountain ski" for me (6', 180lbs")
I only have 3 runs on the 190, which I thought I was going to fall in love with immediately, but I was surprised to find it was much stiffer, to the point where I wasn't taking full advantage of the flex (keep in mind I''m not a very chargy skier)
So yeah, I'd say go with the 190
I feel this, I demoed them last weekend and I felt as if they were wayyy stiffer than the older models (14-15 and older) I was also riding the 178 and I'm 6' 155lbs.
I guess I was expecting them to feel like the 13/14 SFB's I had but they were a way different feel since they were redesigned.
