Arv 96 - 177cm or 184cm?

hello! i'd greatly appreciate some advice.
I'm 5'11 and 90kg.

I have a pair of 178cm blends set 2cms back from centre
I have a pair of 185 bentchetlers 2.5 back from centre

basically I love my blends but because i'm quite a heavy set guy (or just a gaper) when going off big jumps I can feel a bit wobbly/unstable. Was thinking about getting a pair of arvs as they sound like they are more firm and will help my jump game out. I barely ever slide rails, just the odd nose bonk really.

So should I get the 177s - I'm a little bit hesitant to go smaller than my belnds, especially as i will centre mount them so ill loose 3cms off the front.
Or the 184s? - Im scared they are gonna feel a bit much, I'm sure they will be a lot lighter than my bentchetlers but I havent even pulled a 3 out on my pow skis because of how heavy they feel compared to the blends.

The other option was get the 178 edollos and centre-mount them - but from what I can tell they are pretty noodle like my blends.

All advice and thoughts are very much appreciated.
