Some good, funny and interesting points here so far
Giro used to have downhill TTs if I'm not mistaken
really

.. a downhill TT is far fetched hehe, makes me think of some Redbull event rather than a GT
9. Stage with two steep cat 1 climbs (no valley in between) finishing after technical descent
technical descent finish would be good alternative to downhill TT instead
Two to three time trials, however, only one would be 50km+, the other would be around 20km and would ideally be similar in nature to the one that was used in Pais Vasco earlier this season, tight, hilly, and technical; the third being a prologue/TTT and not every year.
Yes, very different types of TT's would be more interesting
add one Alberto Contador Velasco and any lack of excitement is resolved
Contador's style provides excitement indeed, on the other hand sometimes dominance too

Ideally all top dogs should be there at 100% .. but that's just utopia and without the reach of the organizers
get ride of race radio
...HRM and power meters.
I hope they do get rid of the race radio, it even causes crashes due to the nervousness of the DS etc. I hadn't thought about the power meters though, I think it's influence may not be underestimated! Good point (HRM says far far less so I dont mind that)
bring back bonus seconds. It makes GC contenders want to fight for position 1-3 more.
Yep, that's why I said it too! Don't know why they don't use it anymore, just stupid
I always liked the last day TT in the Giro. Now the last stage of the TDF is negligible cus nothing happens beside the sprint. I doubt they will touch that but maybe a flat TT in paris can be replace that.
