well, there is 2 models. The one with alot of flex and the other when is more like " closer to the ground and less flex"
The one with flex is made for cruising.
The other one is for downhill, shreding and etc..
If you want to cruise, pick big wheel, it will give you alot of acceleration

It also depends on you, I stepped on both, and i personally didnt like the one with alot of flex and the other one is more stable ( thats why its made for shreding.. )
Go to your local store and try them
