Yeah, I dunno. Lots of TL tyres are pretty burly. The GP5000 TL 25mm is ~300g and nothing like a "supple" race tyre on account of the air tight liner and the extra burly beads. Imo, is all extremely exaggerated and magnified through the lens of the internet. Its just like on the HIFI forums, ppl arguing to the end of time that one digital cable is muuuch better than the other and compressed music sound like garbage and blah, blah, blah! Sure, the difference is non zero, but more often than not its miniscule and even below threshold of human perception. Same with tyres. Ride your protected tyres at 1 psi less then your supple race day tyres and you be fine, except your metric century will be 5 minutes more. Outside of pro racing for money, - Who gives a damn? You wouldn't even notice without a stopwatch :-)
