well more than structure its a workability (right word?) issue, you would want to have vertical grain on the strips ideally, vertical grain strips come out from the cut of flatsawn and, if im not wrong, flat sawn wood its cheaper than the quartersawn... The point im trying to make is that if you look for the best flatsawn board you can find in normal stores you would end with the cut you want and spend less, not really worth to go buy furniture grade cedar just because its the best wood when, with a little time, you can find great boards in the fencing pile.

: Ok so I'm brand new at this...How important is it to get flat sawn cedar vs
: vertical grain before cutting out the strips?
