Sorry, I seemed to have missed this post. I would suggest looking at the EVO 70. The EVOs are easier to turn on a wave with less sailor input relative to the boards size, so therefor I think EVOs are better than Kodes. The EVO 70 is looser than the 75 and still has enough volume and stability for your 14 year old, so I think this size is the best. Moreover, all models of the EVO 70 from 04 to present have been very good (with the 07 and forwards a step up in looseness and smoothness). So it should be possible to find something used or last years model at a better price.
The EVO 66 (09) exists in a prokids version which is priced lower, but it is in reality quite a lot smaller than the EVO 70. Maybe too small at this stage.
