Let me know which you would be interested in. Also, as correctly mentioned already, if you search under Allen Magnum, APS or similiar titles you should get alot of reading on here. I am pretty windy when I type and there are getting to be alot of guys using the Allen Magnums so they have posted good data and stories as well.
Thanks for the interest.
