Practice is great but if you apply the same practice to the Swaro you will be better off. Hoser stages are no fun with an ACOG.
I have fallen in love with my DD Irons, you know the 45 degree ones? That is what I use for the hoser stages. I even put a fiber optic front sight on the front. There is that decision you have to make though, what distance am I comfortable with? I say 20 -25 yds is the edge of hosing with the irons, and that's on a full size ipsc, now they are using the little guys and it just makes it harder!
But I'm still a rookie so take nothing from me, just spouting random personal info.
