The reduced drag would spin rockets over if you weren't careful. 

That does, however, mean that the instability causes by aeros pikes is gone, which is great. 

Not wanting to look a gift horse in the mouth, but it seems that 0.22 has changed aerospikes back to a 0.2 drag coefficient. Why do I care? - well I've spent some of the past two weeks designing and testing a novel Eve return design that relied, in part, on the lower drag of the aerospikes. Oh well, back to the drawing board. I still love you Squad.

Aerospikes in 0.22 - what a drag!
