Replying to FKS 185s on my Park Skis?

So I know what most of you are thinking, if you have to ask, don't use them. However, I am a very heavy skiier, with a large BSL, which means my din hovers around 10-11. I weigh 210 lbs and am 6'5. I just got some 185 Coreupt Colbys and needed a new binding for them, so I saw some FKS 185s for a deal and hopped on it.

Now I'm wondering if the FKS 185's are going to be a good fit for the ski, since they dont have a vertical release and are a bit heavy? I really want a bombproof binding that we all know the FKS to be, but I need something that won't be crazy heavy but release me when I NEED it to.

More and more I read, more I hear that everyone puts the 185s on pow/big mountain skis and not park skis.

Thanks
