I prefer HSFX, in that it has the Lt. wolf's orginal P-51 flight modles for the new Mustangs that preform better than the 'edited' UltarPack versions..

Also if your a P-47 lover like me and your PC and video card are a little dated..

Than you should get HSFX over UltraPack..

In that UltraPack replaced the stock P-47 cocpits with the highly detailed Freddie's cockpits..

Which are beautful but can cuase a big fps hit on your system!
