RE: Which covering?
Well I have used Monokote for the last two planes I have covered with absolutly no problems, very different colors. I allways enjoy the debate about which is better, IMO if you learn how to set up your iron properly and change settings for the roll you are using you will discover you can put on either. I like the colors better from Monokote better than the others.
My advice is try a piece to see where you have to set your iron and then go from their for that roll.
