I will start off by saying I am biased.......
Do the Nixon winglets.
I have flown his 20A and 20C with/without winglets.
For me, I could do my normal "yank and bank" with his winglets.
Just chat with Chip Bearden.....we flew 24's in various configurations decades ago head to head.

I have no clue if Hank can do extensions, may depend on how the ship is registered.

Just my $0.02.....
