Replying to Marker Free 12.0 vs Look PX 12s

Okay I currently have Marker free 12.0s mounted on my Anthems and they just seem sooo heavy and they seem like I just cant flex my tails or tips as much as I should be able to. So I have been looking at some PX 12 jibs and was wondering what the difference would be in the binding weight and just if they would be a overall better binding (which I am sure they would be but I just want some positive feedback)

So I guess what I am asking is how much better would PX12s be than Marker free 12.0s in terms of weight and how much they would allow my ski to flex.

And also if I mounted them would the drilling patterns interfer with the Marker drill patterns?

I hope all my questions made sense so thanks and +k for your help

Oh and if you have any PX 12s to sell for cheap shoot me a PM.
