I have a Flatland, and I ordered it with larger holes on the front as I have no mud problems here in rock land. Have lots of rock, though. They added the holes for me at no extra charge. It doesn't resonate, and has been trail tested to withstand very hard rock attacks. I've hit it several times quite hard, and it certainly took the hit and saved my water pump and clutch cover. I'd buy another Flatland if something were to happen to this one. The performance, fit and finish of the plate led me to purchase their radiator guard as well. Good folks, making great products. Not to say others aren't as good, but I've satisfied myself this one works as advertised.
