Replying to Ski Brakes Keep Bending

So I've come across an issue where my ski brakes will bend a lot, or the heel piece breaks, or both. (perhaps it's my desire to occasionally throw myself around in the park haha). I currently have Marker Squires: 5'10 and 140lbs. So looking to upgrade for next season, and would like suggestions for a better built binding for my park purposes (hitting rails and jumps equally)? Unless it's just me...Is this issue common for all bindings? If so, should I stick to this type of particular binding 'style' instead of pivots? I saw in some forums that the brakes are expensive to replace. Lemme know your thoughts!
