Huge difference, though. You could go with one of the other types and still reap the weight and rolling improvements no matter the weight of the bike. I currently run Michelin Krylion Carbon 23's. I had been using the insanely heavy Bontrager B 25's for 3 seasons when the krylion had been ranked very high in rolling performance and weight savings (235g). I bought a set of the smaller 23's. The weight savings was about 100g per tire plus the much more agile rolling performance. This was on a lighter bike (22lb'ish) Trek 460 racer. The difference was stunning. I immediately was quicker on all my courses.
You would feel the difference on a heavier bike, I'm confident of that.
