It really comes down to the situation and who you are fighting against in the MA vs the type of planes you are both in. Spit16s are incredibly versatile, even finding one lower than you can be a really tough fight given who the pilot is. The spit16 is a beast mode plane because it is capable of so performing maneuvers very quickly. You simply wont beat it in a g14 if they are very inclined with how to perform maneuvers in AH. It's not like being higher than a p47 where it's not that great of a defensive plane. The G14 is a great defensive plane but it still cannot match a spi16 or an la7 very well if they have more speed over you. The key to being a good 109 pilot is to learn defensive maneuvers, set up counter shots, and make quick snap shots as they cross infront of you. I always love fighting spits in my 109s but you have to out fly them with experience knowing what the spit16 is probably going to do, and then counter that with a complex maneuver. If they foil the plan and you get slow in the rolling scissors, the spit16 would typically win. In a 1v1 fight in the DA the spit16 would totally dominate the g14 and A5. The 190A5 is better at BnZ, so if the 190 loses that advantage against a spit16 its pretty much GG.
Grizz was a very good pilot. It wasn't just his aim that was exceptional. He had great understanding of what to do next and timing his maneuvers. One thing that makes some pilots better than others is the timing and control they have over the plane during the maneuver. Timing and control make a huge difference to how the fight plays out. (This includes flaps and throttle timing)
fighting against Bighorn was very interesting because he had perfected the merge to where he could get inside and still climb up to you with much E. He also had very good timing and control.
BadBoy also has great control and E control.
One thing I notice about fighting Latrobe and Joach1m is that they have extremely good roll overs. Grizz was also pretty good at this too. The roll overs in the rolling scissors really allow them to get inside you. Krupnski is also very tough. This is a huge part to being good in 1v1 fights that many people are not excellent at. You begin with the Merge, then the transition to what you want to do after the merge, and then you begin a series of rolling scissors that take a lot of concentration. These rolling scissors are crucial to winning fights. Learning each position of the duel will help you become a better pilot all around in the MA and the DA.
