andrew22222, adjust fuses exposures only(no HDR, no Tone mapping), and there is nothing to blend but issues with your aligning and vignetting(get rid of this in ARC).
And if you'll try to stitch Tone mapped pictures - there will be issues, if settings are harsh.
You should think about priority. What's more crucial for final pano? I you do one mistake in the middle of your bracketing set, Photomatix will correct this simply by shifting, but if you first stitch panoramas by exposures and then feed them to Photomatix - there will be huge issues.
Also I set contrast and blacks to 0 in ACR, because there are many details. It's easy to increase contrast in future, using USM hi radius.
+ use aligning "by correcting shifts" and don't play with adjust blending point.

//Thanks for the link Andrew. I've tried this technique with this tutorial
http://www.ptgui.com/examples/vptutorial.html with no result, the other day. I'll try it again. Nadirs are always time consuming
//I'm considering to buy Nikon D7000 but it only can do 3 bracketing shots and I found great solution using your iPhone/iPod/iPad as a remote(but still need laptop attached) for 20 bones
