First off, Welcome to AH 2! As far as Soda's evaluations, they are a great help. After a year, I still go back there from time to time.
I'm by no means a pro in the 109's. I do like to fly them from time to time. The F model is one of the best 109 turners and can mix it up pretty well in the MA. The only real disadvantages (IMO) are its not too fast, so you're not going to be able to outrun or catch too many others. Secondly, the MG ammo is only 7.9 mm.
On the other hand, the WEP is great and you have a lot of it. Almost 10 minutes if I recall. And if you're into saving perk points, the F is a great plane for that in the MA. I prefer the G-14 or the K in the MA. (This tour, I've gone back to the P47D-40 though) The 30 mm in the K does take practice to aim. Practice is the key there.
Keep flying different planes. I find that I get the most out of my flying time when I try and learn a new ride. I would also recommend coming here to the BBS and asking for advice or going to the TA and asking for help if you run into some problems. There are many great people here that are always willing to help out. (A few dinks too, but ignore them.)
Good luck and hope to see you up there some day.
