im purchasing a new bike for street parks and dirt jumping and i have two options. the kona shonky for 900$ or the rocky mountain flow 2 for 900$. both are newer frames (2011 or 2012) and both have hydro breaks and 26" tires as well as the same warranties.. im slightly taller and heavier at 6'2" @ 260lbs. what would the best frame for me be. im leaning towards the flow because of its boxed tube style frame and looks stronger. the shonky i was looking at looked way thinner then the flow 2 but im still not sure what one is the best. thanks for any help.
