12 and 14

-cheaper
-more elastic travel in toe
-lighter

pivot 15
pros
- toe looks better
- more durable due to metal toe?
- lower stack height
cons
- less elastic travel in toe
- heavier
- cost more
durability of the metal toe of the p15 is debatable as I have never seen a plastic toe fail. Unless you are going to use a CAST SYSTEM, need a din higher then 12 or p15 are cheaper/same price, I would recommend the p12/14
