Hitech, my problem is not the range difference, but the time difference. Such as it is in AHII now I have less than 20 min in my 109 with 100% fuel. Now with fuel management that can be extended quite a bit, however I can't use fuel management in a climb. The most fuel economical way to climb is on WEP.
A typical 109 flight for me with a droptank would be T/O and climb to 25K (6-7 min) cruise while looking for prey (limited to 10 minutes to reserve fuel for RTB), engage enemy (limited to 5 min), extend and climb to conserve fuel (5 min), RTB and land (10 min). It's the climbing part and actual combat that sucks most of my fuel. The cruising part where I can use fuel management is trivial.
Point interceptors are harshly punished by the burn multiplier because the arena is not "compressed" in the vertical. In real life the P-51 could cruise for ages, true, but the point interceptors like the 109 and Spitfire had plenty of fuel to do their job, namely climb, find the enemy and fight. Now I'm limited to about 5 min combat time. There is no realism in this.
