id say make your skip the fun to whatever build you see fit
i personally went 22/21 on lvl30 (not retiring, thats why 22str) and it worked fine, long spear no problem even with only 1wm (if you go for 21/21 you can have 3wm even), pike is a bit slow but works as well
play around with your stf for a while until you found the build which suits your playstyle best
