I think blindness has to be taken shot by shot. Seeing the flag from the tee certainly helps mitigate a blind tee shot. The actual blindness only really matters if an archie is f*)_*ing with us. By that I mean he is sticking in nasty hazards which can easily be hit. If the fairway is generous the blindness doesn't really matter. I often talk about Pennard for blindness because folks go on about all the blind shots. Most are due to being out of position (2nds for #s3, 4, 6, 7,
. A few from the tee don't really matter as we have clear aiming points and can see the flag (#s 8, 9, 14 & 17). There are actually only a few holes I would say are well and properly blind (#s 8, 12 & 17). On eight the ball can end up either side of the fairway and it can be impossible to know which, but one should nearly always find it and the approach is short. 12 is not overly difficult as it is drivable and the 17th is one where I would say the archie is F()_)(ing with us. So blindness can be made a big deal of, when in truth it rarely is an issue for the player who can think a bit.
I wouldn't say if I can't see the ball when it finishes that the shot is blind. The shot requirements can be on view and yet the result blind. This is one of the great advantages of hollows.
