Short answer: take the 300, the 1.4 and the 24-105. Bring the monopod. I live near the Blue Angels home base and frequently spend time at the beach there, so many opportunities for aerial shots during practice, or training aircraft for newbie pilots - for pleasure, I'm a hobbyist and concentrate more on astrophotography. 200mm on FF is way too short; with the 2x it would do well, but I'd still prefer the 300. My 300/4L (non-IS) does well and withstands cropping, I'd use it with a 1.4TC if I had one. I have an old Sigma 400/5.6 Macro, weighs a ton, no aperture control, but a surprisingly sharp lens. Gets heavy without a monopod. For wide I'm limited to the Samyang 8mm, Tokina 11-16 and the depressingly-mediocre-at-best 28-135IS kit lens. 24-105 would do you well in that department.
