If you're coming from marathon plus (also expensive btw) and switch to GP5Ks there will be a day and night difference for sure.
Switching from ultra sports to 4x more expensive GP5ks will have a smaller effect than adjusting front and rear tire pressure for actual weight distribution and most people don't even do that.
It's only weight weening at that point. I'm 194cm 85kg. With two bottles my system weight is 100kg+. Idgaf what my tires weigh
