I shot a 70# alliegance last week as well. It was smokin fast and smooth as silk. I shot several shots through it and thought that it was possibly one of the easiest pulling 70#s I ever pulled. It was actually like 71.5 lbs. To do a little bit of testing on the ease of pull I shot a couple other bows that were in the shop also. All we had @ 70#'s was an extreme and a relfex with the cam.5 system. Both of the other two felt about 8 lbs heavier. I with we had a freedom cam at that weight to compare to but we were out.
The alliegance feels a little bit like a freedom cam, but more constant. Almost like a reverse recurve. It gets easier as you pull. It is stout at first but it seems to start letting up really early.
Bowtech has some new info on their site also

Get out and try one of these bows. They are awesome.
