They are close in a lot of ways. The 38 will zoom better in the vert, but the spit climbs well, so that is a very small window to play in.
At first the 38 will out dive the spit, but the spit catch up because it can out run the 38 once you run out of dive room.
About the only thing the 38 does better is a spiraling climb into the torque of the spit. If you get someone dumb enough to follow you up in a spiraling rope like that, then hes dumb enough to kill in most way anyway
