Have you ever had to remove a simplicity deck or a deere deck? I have... on both brands... And while the simplicity may cut better out of the box, dealing with removing the deck... No thanks!
Why not just get Deere with a 7-Iron and a stripe roller and call it a day (same could be said for the yellow Deere 54C and 62C both of which a stripe roller kit is offered for about $250).
