I've not had much luck finding reviews or comments on these. A search of BF didn't tell me much more than the marketing fluff online did.

Have any of you used them for races that called for a tough tubular? How were they for cornering? Do they feel sluggish/heavy compared to a regular tub? I'm thinking about getting a set to throw on a wheelset I commute on but would also use them for a race coming up this weekend.

any input appreciated.
