IMHO, except for the 262 their performance over the regular planes offered, late war, isn't that great. AR234 can be caught by some of the faster non perk planes, the TA152 is great high, 30K and above, and the tempest is fast also and can maneuver, but a D9, Tiffie low, La7 and pony can get them in the right situation. 262 is boring to me. This my humble opinion of course. When they offer the SR71 I'll spend them <G>
