Hi, I'm 6'0 and around 154 pounds, would going a 153 be too small or just fine?
153 will be just fine. A nice blend of stability and agility.
In more detail:
It will be sweet in the blue park, at tech rail stuff and just kidding around. On bigger pedal to the metal things you should consider a 155. If you only ride rails go for a 151.
I'm 6' 164 lbs and ride a 155 Capita Horroscope which is similar to the Park Pickle. The Pickle is a little stiffer with it's carbon rods, the Horror is more like a Banana.
I find the 155 a bit long for tech rail stuff. It rides like my old 157 K2 Believer (medium/stiff traditional camber). Which is great for jumps and cannonball runs, the reversed camber is not that great at high speed though. The centred contact point tend to be dodgy when riding flat base on harder surfaces.
