In blower pow (cold and dry) you don't have much friction. Stayin on top and planing will have a much larger effect than extruded vs. sintered. And on top of that an extruded base with a good structure will be faster than sintered with no structure. So there's that too.
Camel Toe if you want surfy edge to edge. Hovercraft if you want faster stability.
Sick, you always know what to say. Camel toe in 158 and some tt30's coming 21th of december, thanks Nivek.
