I would think carpet tracks have to have a good track set up too. Just like dirt, when the track is no fun or set up weird people turn away. Next time I am in Vegas going to try 702, RC tracks of Vegas is sweet.

Have not had a lot of experience with cf towers, having a front wing may help save the front tower, rear I don't know. With B5m breaking stuff was so few and far between stopped thinking about it.

Can't wait to see build weight for 17.5 class.
