K2 Poachers vs Line Blends and sizing question.

A bit about me. I'm 6'1, 170 pounds. No f*cking clue why I'm on this site because I suck ass skiing but you guys seem to spread some decent advice. I've been skiing for like 4 years, 20 days a year at max. Also I go to Landgraaf (indoor hall in the Netherlands) like 3-4 times a year. My ski level is intermediate I'd say at most. Am now at the point that skiing switch becomes decently comfortable and 180's and 360's land most of the time. Safe to say I'm a beginner in the park but I'm not afraid to throw new stuff and fall a couple of times.

So this one night my friend and me got drunk again and ordered a set of Salomon NFX's 184. So this was probably the worst idea in history of idea's ever because I could barely throw a 180 at this point so these stiff ass ski's were an absolute nightmare for me on everything exept groomers and medium sized kickers where they saved my shitty landings.

Let's say that money isn't an issue and buying an additional set of ski's is the new plan. I'm looking for a 1 does it all ski which is decent for all types of conditions. This means a bit of park, hitting the sides, groomers another day. My friends all snowboard because they are boring and they jib around quite a bit so a ski that is playful on the mountain too (and in an not steep indoor hall with a funpark) would be preferred. Like I said earlier, 180's and 360's in the park are fun but I'm not planning on landing a cork 7 or some bigger shit like that within any reasonable timespan.

With these things said, I was having doubts between the K2 Poachers and the Line Blends. So my own conclusion was that the Line Blends are probably a bit better due to their playful flex, and I doubt the flex will be an issue with landings for me if I just throw small stuff in the park and on the mountain. Also I'm not the fastest charger on the mountain and prefer to play around a lil bit while going down. So unless you guys think the K2's might be a better choice, I'm sticking with these ones.

Now here comes the tricky part, the sizing. The problem is that the 184 NFX's with my weight (used to be even lighter before, like 155-160) were an absolute hell at the end of the day when the slopes started to get some mogul forming and these ski's became basically a trampoline if I messed up my line just a little bit. This kinda got me thinking about buying a pair of ski's that are a bit smaller then me, however since I read that the Line's got a early rise (could be older model tho) I'm really thinking that a set of Blends 178 that is 7 cm shorter then me is a little bit too short. Any advice?
