The Guttershart is not a strong frame. They specifically designed it to be the lightest chromoly frame available. I would break it in a few weeks. It is for light street and light park, that is it.
The Aurora is not really any good, for the price. It doesnt have anything special for the extra money you are spending on it. Same with all the Premium frames except the Guttershark. They charge you more for nothing. I could understand if they were any different. Look at the other frames in that price range. Sunday Soundwave, Sunday Funday 2.1, Guerra Moose, S&M Frames all around. For the same price as a Guttershart you can get a Terrible One, which has a much better quality. The way i see it, if you wanna charge as much as the nicest frames, you better include the quality you pay for. Hell, if Premium had the same frames for 250 bucks, I'd be on it like stink on poop, but it isnt.
Let's look at what Premium is. They were designed to be high quality Haros. When in reality, that is what the original idea was for them, the only frame that ever succeeded in honoring what they were made for was the Guttershark. In that sense, that would be the only Premium id ever buy, because it is a true Premium.
