David,

This seems like a conversation you should have with your fitter.  Without knowing anything about your swing, it's impossible to suggest which would be better for you, even though the specs are similar for both.

I have had the tour issue and lovedit but  I would say hit the AMT I thought it was the best shaft i have hit in irons yet  by far!!!!! 

You know what? In my opinion, asking for peoples opinion is kind of fun, I do it myself. But spending money on peoples opinion isn't fun. Take your time, try to hit both before you make a sound decision based on how you feel. 'After all is said and done' as one might say, it comes down to what pleases you.
