Need Ski Advice

Maybe like 159 do

*domains? Pretty solid ski. Or the armada park ski for kids. Coda I believe

bump i like a fairly stiff ski i demoed the surface next time in a 155 and they were sick

bump thinking about afterbangs, they a good ski? also whats the flex?

If you prefer stiffer skis I would stay away from the A-bang.  While at your size you certainly do fit into some junior boards but your options that include a stiffer flex are going to typically be wider all mtn/pow type skis.  The one that I can think of is the Volkl Gotama Jr, it comes in a 158 which might seem long but it is full rocker but it is a very low and gradual rocker so it still should be decent in the park.  After that you start talking adult skis pretty quick, the Armada El Rey could be a good choice in at 157cm at $399, my cousin has ten pounds on you and maybe two inches and that what he is on, or the Nordica Double Six in a 156cm it's mid stiff and $399,  or the Volkl Alley in a 158 cm is a pretty good ski for $299.
Here is the Double Six
