Thanks for the replies and info - It's a tough decision between the Knight and the T/C because from what I've read and seen they are pretty evenly matched in the quality dept. I've not looked into the Whites because I read here that they were having a hard time financially (bottom of the page) - http://www.chuckhawks.com/white98_Elite.htm - but perhaps this is not the case.

I've read that the T/C is a little easier to clean - any thoughts on this? Also, should I spring for the extra length in the XR or Bighorn versions or will I be limited due to the use of conicals anyway?

How is the trigger on the Black Diamond XR cayugad? The Bighorn is adjustable which appeals to me but if the Black Diamond is pretty good then maybe it's a wash.
