Since I don't want the hassle of more messages in my inbox from retailers I'll likely only buy from once or twice, I stuck with Ebay and chose a pair of Vittoria Corsa Control G 2.0s. I note a lot of members seem to like the Corsa series in clinchers, and probably some are using the tubulars, too. After watching a review video by a real person, I think a pair of these is just the ticket for the high pressure and durability I seek.
Hopefully these arrive quickly, and I can get them on early next week - the Davidson is in serious need of the final check-ride to determine if all is indeed 100% back to normal after the 'love tap'.
