I think the 13 is way better construction than the CCTS but you can't use a kick with the 13 very easily. I have both by the way as well as the 8 and like the sigelei's more.
Thanks for the answer! I have a #19 on order already and planned on ordering a CCTS today. When you say "can't use a kick with the 13 very easily" does that mean *impossible* without a bunch of retooling? I really have no desire to run a kick in anything but I am still curious about options...
