That is a great setup! Depending on your binding angles, you might want to consider the wide version.
I ride on a Custom 3D 156 with Missions on the pipe ,a Custom ICS 158 with Triad EST ,and a 158 Operator/Missions
for everything else .
It will all depend on which boot you have and your riding angles. Best way to be sure is to possibly try your setup
at a local retailler.Really hard to give you a definite answer through a email if toe drag would be an issue .
Sort of the same situation as if you wore a size 10 boot ,would you use a med or large burton binding .
As far as your other question if the Custom would be good for the park is a resounding Yes !
The Custom is the most widely used board in burton's lineup .It's a great all purpose board .
well unfortunately i was planning on gettin the board online i cannot find last years model board so like i said the lineup is 156cm burton custom ics with the cartel bindings and what kind of boot would you recommend?
