Reached just a little to far, first part is correct, everything in red is wrong.
The duck tail increased drag and cut a few mph off the top end speed as well. There is more downforce with the Duck Tail, and better cooling. The later wings/tails provided similar modest down force but much less drag.
A chin spoiler is a good idea with or without a tail. If you add a tail of any kind, a chin spoiler is a must.
