I have noticed recently that my harness was digging into my ribs instead of sliding up. After a quick inspection I noticed the screws connecting to the spreader bar were loose causing the front of the harness to twist when the kite is up high. The screws now seem to be ceased and I can't loosen or tighten them without wrecking the head of the screw in the process. Has anyone else had this problem? I'm not sure if i have broken something or not. I think I may have just bent the screws when they were loose and thats why they won't tighten up? Any suggestions would be appreciated.
