Chris, extrude polygon island is inside the compound of apply extrude polygon along axis :) I tried it anyways from your suggestion by bypassing the merge polygons and plugging directly into integer array - it sort of works with low numbers of random selection but breaks dramatically with higher numbers, thanks for the pointer though!
