Cit,
I can't argue with you about us "jug dweebs" being spoiled

. Like most spoiled children we always want more.
I do disagree with you on the fact that all three jugs fly the same. Since it's introduction I have flown little else and though the -30 and -25 have only suttle differences, the -11 is very different in my opinion. Here is something I wrote in the training forum about those differences:
P-47-D-30: This is my Jabo plane of choice. It can carry up to two 1k bombs under the wings and ten rockets and a single 500lbr under the fuselage. It has the most horspower of the three, it will pull 52" of mp at 100% and 65" mp in wep. It also is the only one of the three with dive brakes. Without ordanance attached to it it is one of the better of the very high altitude flyers. It is in it's element over 25k.
P-47-D-25: This one is a "bubble top" as is the -30. It is a little lighter (300lbs is the figure I understand it to be). It only pulls 49" of mp at 100% and 60" in wep. It can carry almost the same loadout as the -30 with the exception of the rockets. It only carries 6 of those and they are shot out of tubes that stay with the plane after the rockets are shot. It feels a bit lighter to me and used to be my ride of choice for fighter sweeps because it did tend to fly better at the lower alts and seemed to turn a bit better too. It also outclimbed the -30 at full loadout. It is another good one over 25k. Both it and the D-30 use the paddle blade prop and water injection. It gives up a little in climb to the -30 over 20k due to the reduced wep. It's green and it is harder to see down low and if flown with icons turned off and is harder to pick out from the terrain than the D-30. It is painted in the Brasilian "Senta Pua" squadron colors.
P-47-D-11: My current favorite. The lightest of the three though I don't know what the figure is. It is the "Razorback" and the extra side area makes it more stable in low speed turns. It is really a sweet ride. I carries less fuel than the other two and can carry only one 500lb bomb or a external tank on the centerline under the fuselage. It will only pull 49" mp at 100% throttle and 60" at wep like the -25 but it doesn't have the paddle blade prop like the other two. That prop makes a lot of difference in how it climbs. This one gives up over 250 fpm over 20k to the other two. It does turn much better at low altitude than the other two but also gives up some visability due to the canopy frames and the restricted 6 view. It is green like the -25 and colored in the 56FG squadron colors.
If we had all three of the 38's you listed I would probably have to spend as much time in each to be able to notice the differences I notice in the 47s. To do that though would keep me from flying the plane I love most though...
