Reshafting my 712 AP1's with a lighter shaft

I recently ordered a set of AP1's with TTDG S300 shafts.  I've played them about 8 - 10 rounds, but find the overall weight of the club to be a little on the heavy side.  I've played the TTDGSL S300 for the past several years in other irons sets prior to this set, and decided to reshaft these irons with this shaft to make them a little lighter.  I got my shafts the other day and began the process of pulling the existing shaft (I started with the 5 iron) and noticed when I pulled it out that there appears to be a brass tip weight plug in the tip of the shaft.  I did not think of tip weighting before I ordered my new shafts, but then again I've reshafted clubs a few times before and this is the first time I've seen these used.  My question is - - would I need tip weights for the TTDGSL shaft?  My thinking is the tip weight was used to help offset the overall weight of the shaft since it is a little on the heavy side and, since the TTDGSL is a much lighter shaft, a tip weight would not be needed.  Any thoughts?? Thank you:)

I have found the same thing. I am reshafting back SL's from DG's and found the tip weights. I didn't think they would even use them in a mass production club. Because I am lengthening the shaft which will increase the swingweight I tried assembling without the weights. I dry fitted one of the clubs together and slapped on a cut grip and then checked the swingweight. It was right on at D2. I am going to go through the same process with the rest of the set today and then hopefully finish putting them together. I wonder how many others have found this same thing.

Well I finished checking the swingweights yesterday and they were all right around D3 so considering I added 3/4" that is not too bad. I could go to a heavier grip but I am going to play with them as is for now. Don't think I can tell the difference between D2 and D3 anyway.
