@ThrillerFan after looking at your game and my Kotronias book I think you are being too quick to judge the line in white’s favour. Kotronias says that while 15...Qe8 is popular, it is not very good. He gives 15...a6! as the best move. Additionally, you would have had a slightly worse position but nonetheless a more tenable one if u had played 17...dxc5 rather than Ng6, which Kotronias deems dubious, just like he deems 15...Qe8. I would look into a6 before giving up the KID over 13. Rc1.

The whole ...Rf6-h6 line is suspect at best. 13...Ng6 is way a better move by the current theoretical standards.
While it is tough to do so much work on a line as my good friend vassilis Kotronias has done, and then abandon the ship, I think it's time to bury 13...Rf6.
Vassilis misses 27.Qc8 in his analysis. The results in Correspondence chess (eleven games, with white scoring 100%), says that the line is dead for good.
Of course when meeting a class level opponent you'd rather expect his TN at move seven, not twenty-seven, but in CC we have completely abandoned the 13...Rf6 line in favor of 13...Ng6.
It also seems that the conservative 13...Rf7 is quite playable, but the aggressive 13...Rf6 is definitely busted.

Thanks for your input. I will definitely look at Ng6 and Rf7 now. I’d think that in a practical game Rf6 is probably playable and dangerous, but it is not so surprising that such a bold took lift is not fully playable at the correspondence level.
