Looks like you've pretty well got it figured out.
Doesn't do a sustained turn as well as spit or nik, but you can suprise them if you have E.
Good guns but like you said, slower rate of fire, and muzzle velocity. Lots of ammo, this is one of my fav things about this bird.
Come high to the fight, watch for easy kills.
Planes already engaged, planes limping home wounded, etc.
It dives much better than the 109's and turns a bit better. Watch out for the La's & yaks, they'll eat you.
205 is VERY popular in the CT for desert setups.
That desert camo maks it very hard to spot down low. Bit tougher to survive in the MA envoirment.
My most kills per single sortie was in a 205 vulching a small field. They just kept coming up.

When you get tired of the poor view try moving up to the yak.
