I can understand that.
Just to temp you further though, editvoicepack changes some things that were missing from the default FSX
For instance when you land, you are directed to contact ground immediately, editvoicepack waits until you have left the runway.
Your pilot will say 'changing to ground on xxx.xx thanks, buh-bye' (notice the extra 'friendliness')
and finally, when communicating, the ATC has background rado chatter -
in all it's a 'pain / problem / configuration free' installation, possibly the best thing about this little upgrade.
Also, you will be able to have the pilot say 'is type Corsair' easily enough with v4.0 - obviously, the choice is still yours
