Replying to Kind of what binding/fks 140s?

So i am in the process of buying bindings for next year. I bought 171 pipe cleaners as my park skis and im seriously considering buying the rossi fks 140s. My budget is like $250. I have jesters on my other skis and i love them but they are a little overpriced imo and a little heavy for park skis. I am an aggressive park skier i guess and i broke a pair of bindings this past season so im worried about durability...

so now to the main point of the thread. I have heard a lot of good things about the fks 140's but a few people have mentioned issues with the plastic toepiece. how big of a problem is this? I dont have the money/im not heavy enough to upgrade to the 180's (i weigh ~160 lbs and im 5'9" and 16 years old). Will these bindings last me through a couple of seasons? and if not what better bindings would you recommend?
