Hi coco .In the Alana?
the 10.6 will be faster to paddle and surfs nice .it will get around sections easier ..( broken wave faces)
the 9.5 Alana ..is pretty much a wave board .only .
The 10.6 can be ridden as a single fin as well as a thruster ..
the 9.5 it works as a thruster.
both are good ,but you can do more with the 10.6 .
If you are going to go for a long paddle with your friends .the 10.6 is better .
if your flat water paddling take the side fins out of the 10.6 ,less drag.
it s fine will just the 9' rear fin .
