I'm 5'8 160lb.
What would be an ideal size for me for all around?
I will be going to the park 95% of the time.
I was looking at 151 but someone said always go higher than lower?
I'm the same as you, pretty much park all day.
I'm 5'10 150 and I just bought a 152 for park. I think 151 would be good, I'd say the lowest you could go and ride comfortably would be 147. Longest for park, dunno 55 maybe. I rode a 155 in the park two days ago and it wasn't too hard to whip around.
