Was going to add, the worst thing to do with a Mossie is load it for some 4 hr mission with 100 gas.
You dont need the extra 1000 lbs of weight. Under no circumstances should you roll a Mossie for MA combat with more than 50 gas internal. You will likely be going 20 miles max, and dogfighting below 8k. You dont need an endurance more than 35 minutes. If you are going on some super long range mission to go bomb something, fine and dandy, but not for a straight dogfight mission.
I find 25 gas and DTs the best load, and I dump my 303 ammo after I roll, and keep 600 rpg for the 20mm.
A thermos of tea is preffered, but not required.
