Im in the same position, and I am leaning toward Python because of the designs, but star guard looks great. I still am looking at Customguards.com but I not sure about their design process, but they have quality CMG.
Python! Scott made me the coolest looking mouthguard eva! and his customer service is second to none!
I just received my kit to make my mold from Python Guards and I will confirm what Tiger Shark said...Scott is wonderful and easy to work with. I will post a review once I receive my guard. I have 2 Gladiator Guards and they fit nice, but the artwork isn't that great...but that has nothing to do with the performance and so far all my teeth are still in place. :icon_chee
I haven't received the guard yet...injust received the kit to make my mold...i was just commenting that Scott has been great to work with so far.
