Dunno man. I'm having second thoughts about mine. Even at speed, they feel a bit..disjointed from the ground if that makes any sense?
On the other hand, G-Ones are awesome, if a bit too big. I think 46/7 mm is as big as I'd go for a slick-ish tyre.
to be fair I had not ridden with the Horizon, only the Compass 48mm which have seen it's share of commuting in London, abet at 40psi instead of 25psi (for regular riding).
Here's the thing, with those tyres, it become quite obvious how much they do squirm at very low speed when at an idea pressure.
However, once you get up to speed (by that I mean 10-15mph), it start to float nicely and still easy to ride.
It's just the very low speed cornering where the massive tyres become fairly obvious.
