I know Infinity is kind of hush, hush on this site. Just curious if anyone has an opinion or insight on the difference between the Primus 160 and the Alpha 20. On paper they appear the same, however we all know that to be not true. I have yet to A and B them. I was wondering if the difference in price was actually worth it. The Primus 160 is very comparible on paper and is the higher price for the 20's worth it? Any thoughts would be helpful...thanks.
