I dont know how the NH 7 is , but I did Bellary - hangal-challakere-hiriyur(nh4 from now on) -sira -tumkur -nelamagala-blore one week back .
Bellary to hiriyur is superb , perfect banking everywhere , except the rumble strips .From hiriyur again its perfect NH4 till blore .
You have take a deviation from kurnool and come to bellary . BTW I dont know how is the road condition from kurnool to Bellary .But Bellary to Bangalore no problem . This would be little long .
Here is Bellary to blore road .A Must do road

.
