I'm actually shocked at how different the two are. The Rocket is 3-5 boards stronger, it revs stronger in the mids, and the reaction shape is very different. While the Hyroad is very smooth and continuous, the Rocket I think is actually cleaner through the heads, with a quicker, cleaner read off the dry. I thought I was going to have a ton of overlap there, but I really don't think they're anywhere close. The difference in shape is what really stands out the most.
To make another comparison, to me it's like the difference between the Revolt and the Revolt Vengeance, or maybe better yet the IQ Tour Fusion and the Tour Solid, those two act nothing alike.
So how much, if any, is it different from a Hy-Road? Besides that one is blue and one is orange.
