and this is precisely why some form of TT should be in literally every stage race (as it used to be).
if you have balance, then you also have the conflict between the better climber all-around rider and the better rouleur all-around rider. If Remco gains even 10 seconds in the opening TT at the giro, that changes everything, all tactics. Assuming Rog is the better climber (or at least finisher), then he now has to find the time on the road. Maybe he finds it and takes pink. Then maybe remco takes it back during the second week TT. Then Rog takes it back in the last week mountains, setting up an exciting final TT that includes both disciplines...
That is precisely how stage races are supposed to be fought out.
The recent routes with little to no TT do not serve cycling.
The TT is an integral part of the sport. This modern trend of climbing is the only thing that counts is as much of an abomination as the Lance/Ullrich only peaking for the tour crap from 20 years ago
