Steve, Lead tape applied to the head is the absolute best way to swingwieght without changing other characteristics of the finished club. The problem with lead tape is that it is a visible change. Many customers don't like that. So the only way to close the gap betwen heads is to put weight in the hosel. Will it change the COG? Yes. Will it change the COG enough to effect the average golfer? I don't think so.
Remember that the most important thing is show a steady progression between clubs. Seven gram head separation is what we want. However, six grams separation between clubs throughout the set is just as acceptable. The point is "steady progression". This applies to shaft weight as well as head weight if you are to build a swingweight balanced set. You have 11 grams separation between your 4 and 5. That worries you, and it should. However it's not a show stopper. All you have to do now is pull out the calculator and do math to determine the progression target for your set. (In my case I just take off my shoes :-) I hope this helps.
