Chad, you may also want a dehumidifier down there in your basement. It will keep things drier and it will feel significantly warmer.
The -10 is a tremendously different airplane than the -7. I don't see someone having a hard time deceiding between those 2. The -7 and -9 choice, well... THAT could be a hard one!
The -12, on the other hand COULD detract from the -7 sales. I see the older guy who is tetering on losing a medical, wondering what he is going to build and if he can finish it before he dies choosing the -12 instead.
That guy may also choose the -12 instead of the -4! Obviously the -12 will be all pre-punched and Light Sport.
Besides all that stuff, kit building in general is taking off like a SHOT! It is truly a new, alternative hobby! I can't believe how many pop up builders I keep on hearing about!
New England ain't no So. Cal or Texas... YET!
