Dood, can you say "Flying Beefsteak Tomato"?
Not a park skier, but I can tell you some thing about some of those bindings you're looking at.
Your binding DIN range is related to both your size and your overall ability level. Without knowing the latter, it would seem to me that you might be better off on a > DIN 12 binding, although it may not be as critical as in the case of, say, big mountain freeriding (ie freaking fast on varied & unpredictable snow, where losing a ski might be disasterous, possibly fatal).
To that end, people use Look/Dynastar/Rossignol PX## and P## bindings because they're dependable (established by a fairly long history) bindings that have a great of amount of heel elasticity (i.e. they keep you in). They are also available in high-DIN, metal-bodied versions for those who cannot afford to F-up (again, big mountain freeriders). They have two downsides: 1) they're heavy, even the non-metal-bodied versions; and 2) some versions feature a high binding delta, which to say that the binding leans you forward in your stance. In general, binding delta is a personal thing for general skiing, but AFAIK park skiers prefer a binding with little-to-no binding delta. That said, binding delta can be adjusted by adding shims under the binding, which is what I do with my non-park skiing Looks/Dynastars/Rossignols.
The Marker Jester/Griffon are relatively new, mostly-plastic binding derived from the development of the Marker Duke/Baron AT bindings. they're light, and feature very little binding delta. These attributes would make them seem ideal for park, but because they were derived from the development of AT bindings (which necessarily needs to have additional mechanisms under the boot sole), they feature a significant amount of lift (they raise your boots pretty high off the skis), which is a downside for park use. Also, being derived from AT bindings means that the construction is slightly shifted toward the "reduced weight" side of the "reduced weight <---> bombproof burliness" continuum of construction, hence the mostly-plastic design even in the higher-DIN Jester. On TGR, there are reports of failure with the Duke/Baron AFD, which is partially shared with the Jester/Griffon. However, it seems like most instances involve the use of rocker-soled AT boots, so this may not be applicable.
edit: ramp angle ~ binding delta.
