If you like the 205, you might try your luck in the Ki61. I personally think they fly alike, but the Ki has 20mms in the nose and they are deadly.
I disagree, their strengths are different. Yes the Ki-61 cannons are somewhat more deadly than those of the 205, but you run out of them way faster than in the 205 - you need to be accurate, spray and pray does not work like in the Macchi. In the Ki, I almost always have to RTB because I run out of ammo (even with only 50% fuel taken) before I have to get some fuel. In the 205, its exactly the opposite.
Coming from a 205 the Ki feels slow and lazy, but it's handling in low to medium speeds is much better. You can afford to stay in the fight longer, but if you need to bug out, the Ki suffers compared to the 205, it just cannot extend quickly enough.
I really like them both, but I feel they are very different beasts that require different approaches for success
