@pmvelu,
Go to Nandi Hills this weekend and try the last hairpin band a couple of times - you have the confidence now,, most of the turns on Ooty ghat are similar... use horns (to make others aware) while at every hair-pin band, avoid crossing a vehicle (i'm sure you are not going to overtake one here)on a hair-pin band and you are good..
Its not difficult for sure.. do that in the day light and if you and Suvi are going together, that would be more comfy...almost all of the hair-pin bands can be done in 2nd gear and do the same thing while descending down - if you can find another vehicle going at moderate speed, simply follow it with 25 ft distance on ghat section...
I would like to do that ghat anytime of the day (liked better in night though

)..
I went to Wayanad a fortnight back and from there only we decided to go to Ooty, we came all the way till Gudalur from Kalapetta and from there we took the Thepakaddu road (i.e. masinagudi route) but did not go Gudalur<> Ooty route, that road is in very bad conditions and you may take hours!! I found that the difference is only about extra 30 KMs (or even less) when you take masinagudi but thats a better route.. This time I have found that the roads in mudumalai forest have come to shape now - looks like that complete road in mudumalai WLS is redone - its still narrow though, but better than the road after masinagudi where you HAVE to go off the road to let oncoming vehicle cross and the edges on this piece of road is horrible as already explained by many here....
Its really a nice route - go for it..
