Replying to On3p FT or Jmos?

I'm 5'8'' 170 looking to buy my first pair of skis. I plan on having multiple skis in the future for different conditions and what i want to do but for now im just looking to get my first pair of skis to progress. I recently switched over from snowboarding this year and i've been skiing on my dads 162 Solomon enduro skis. I've done a lot of research and I really like what i hear about On3p so I really want to buy a pair of their skis. As the title says I have a choice between the 171 FT or the 176 Jmos as those are they only sizes available right now in those skis that i can find online. I know one is more park oriented and the other is more of an all mountain ski. With the sizes available is there one I should just rule out? Any feedback I could get on what ski to pick would help so much!
