Addvance or Sweet potato?

[cuttlefish]

What's going to catch small wave easier and plane better over dead sections...a 6'10" Addvance or a 6' Sweet potato?
Fair comparison because even though there's a litreage difference there is a also a difference in length, rocker and outlines which factor in.
The Addvance was hailed as a longboard alternative by using foam rather than outright length to even the playing field.
Now we have the newer kid on the block with the Sweet potato which again uses uber foam but with more parrallel rails and lower rocker to achieve easy planing speed.
Some discussion on the differences/merits of both may be useful since there will be those trying to decide inbetween the two styles of getting ones fair share in smaller and/or crowded conditions.
