Hi all, I'm in a bit of a odd situation lately and request some help to resolve it. I've been using Taylor Made 320 irons with S90 rifle shafts for about ten years now and absolutely love them. I recently started reading internet content and found out that I may be using the wrong stiffness of shaft. I've been told I have a smooth swing and I hit my 5 iron about 150 yards so I bought a used set of regular shaft 320's for a good price. Additionally, I also bought a Tour Preferred CB 6i and also RBZ Max 6 iron both in regular graphite shaft. I've hit with all clubs with regular shafts and haven't been able to get any distance on the clubs (now it seems I'm hitting the six iron 125 yards or about twenty yards shorter than my normal swing), additionally, I have also established a nasty hook on most of the shots I've taken. Normally, I hit my irons dead staight with very accurate shots and now I can't do anything. I don't want to abandon the regular shafts yet but I'm really confused as to why the clubs would hook instead of slice, as I would have expected if they were too flexible for me. I've sold my old set in stiff flex so I'm in a little bit of a bind right now but I'm hoping that there's something that I'm not thinking about for this problem. I was thinking of trying the CB's or RBZ max in stiff but would prefer to figure out this current problem. I'm hoping it could be in my mechanics but I haven't changed my swing any since buying the new clubs. One more thing I haven't talked about, I'm overseas and probably won't be able to get a professional fit right now so that's not in my thinking at the moment. When I return home, this will be an option. Any help would be appreciated. Thanks
