I have used TGK238.5 and retail YTPP, they are somehow similar but still different. It felt like the TGK wasnt as stiff and had a different flex to it. It had the exact same specs as the retail version, it could be the polarized set up with silicone and lead at 12 that did it but it played better IMO.
I agree.
I had a retail Youtek Prestige Pro (YTPP) and then bought 4 TGK 238.5 setup just like the retail Youtek Prestige Pro - and while they're definitely are similarities between the two frames, they just feel different.
The TGK 238.5 feels softer and more flexy than the retail YTPP - wheter it's because of the silicone in the handle and the lead tape under the cap grommets and maybe some extra material stuffed inside the tubes, I don't know - fact just is that TGK 238.5 with the same balance, weight and swing weight as the retail Youtek prestige pro feels quite a bit different compared to the retail YTPP !
We will never be able to answer the question from the OP, unless you are an insider at Head HQ, and they would be totally stupid if they revealed the truth in here on TT - so the question will never be fully answered
