I recently purchased a windstalker to put on my '06 allegiance and had a couple of questions for everyone. I searched the forums for something like this and didn't find exactly what I was looking for. I installed the windstalker and properly adjusted it (I think). I took it to the range and noticed a fairly large change in the way the bow was sighted in. I had to adjust windage and distance. Is this normal? I know from other threads that it may be necessary to give the string a twist or 2 to sorrect the letoff, but this is different. Maybe it just needs tuned... Any suggestions?
