I really hope twin tails stay in regular production because I really like them and have always wished there were lots of them on the market. I don't even skate switch much except for really basic flatground tricks, but I skate my trucks the exact same tightness, and with asymmetrical boards, the back truck would always get looser than the front, which I was not a fan of. With twins, I don't have to worry about rotating my trucks now, and the same goes for wheels, which makes setup way faster.
