I have 25 TGs on the Raleigh, 25 non-TGs on the Centurion. I'm not sure I can feel any difference, maybe because the bikes themselves are so different. I've ridden the Raleigh on 75 miles rides, never felt bothered by the tires, did feel comfortable knowing it had "flat protection" of a sort. You might feel the difference if you keep your tires at lower pressure. I run mine at or up near their max.
