I would say that unperking the C-Hog could be a fix to this issue. It's just a difficult situation at times since most of the unperked rides can't really compete with the 16.
Personally, I had just watched an F6F show on the History Channel when I started playing this game, so that was my first ride, I then moved over to the spitfires for a bit, and then gravitated towards the P-51's. I agree that there is merit in leaving the XVI unperked as long as it's balanced in terms of another unperked ride that can compete as equals with it. I get the feeling that the C-Hog is widely considered it's equal?
P.S. My post before was just me showing that everything is subjective, I wasn't taking a stance one way or another. I was just saying that it's really hard to have an argument about something like this because people see things so many different ways and naturally will use information and wording to aid their argument. I think what the majority of people are calling for is just as stated above, although I fear if we unperk the C-Hog, we're going to see as many of them as we see Spitfires, and the skies will become even more unfriendly to those who take up other rides. It'd be nice to see a trial week or something like that to get a feel for it.
