Chase T is right. YOU need to demo. I honesly wouldnt compare it to the era but more like a Premier that hauls. No crazy gimicks. The tips are dished out to reduce swing weight for spins, surface tricks, ect. I would definatly check it out.
From what I hear Ruck is riding this board and loves it. So if you have a similar preference to the premier, the older era 07,08, or the 3DS Id go with the B-Side. Like i said earlier i have no clue how the new murray rides, but id love to check it out for sure
