What is everyones opinions on blade setups? For discharging and mulching. I can't decide how i want to set it up. I have never run doubles before thought i may try it. Do you have to use a "+" bracket or can you just tighten them in the perpendicular pattern without the +? I have heard good things about Gator mulching blades but there are a couple of different ones...hmm...which ones??... Of course i am open to different brands and setups...that is what you guys are here for!!!
