Bad Ray Wu strip or Pixie4 cant handle it?

[brichi]

thats my game plan, with 50 pixel or 100 pixel, 1 16 foot covers 2 arches, I want to do 8 arches so 4 strips, just debating 100 pixels or 50.  the 100 pixel strip seems like tinier pixels obviously not sure if they are brighter, I need to build one of each and compare
