Is it just me or does it seem like the top skim pros are moving from a “twin tip” style skim board to one with more of a round/thumb tail?

P-5 still sells the DD Pro Carbon but they added the D-Diamond and it seems that Drew is ridding the diamond in every video posted within the last year.

Additionally the ’13 Keenan Pro seems to be moving in the same direction:

Thoughts?
