DA, you tried. Kind of like someone asking for help then questioning said help. Chad gave his opinion and most people would then ask how would you go about tuning for carbine length. Chad is one of the few people I know who always offers help because he loves to share his vast knowledge. Like a mentor. I did that at my last job with my sysadmins. I have known many people who have vast knoweldge and never offer help- if they do, for a cost. Chad is also one of the most caring people I know. But, whatever.
