Andrew... I have worn both 09 LTDs.
The watsons are stiffer and tighter around the top of your foot, Ive heard Watson does this on purpose.
Shanes have a tish more flex and are definately a lil looser on top of the foot. I think the Shane has stiffened up a little bit for 09. I could be wrong.
Bottom line there both sick and you wont be dissapointed either way
