I struggled with the decision to put the pulled or the solid rivets in there, after doing the solid, it was not that bad. I used a ground down double offset set and a good heavy bar. It is easy to reach the inside of the leading edge from both ends if you do not have the tank on.
I can imagine that trying to get the puller on some of them rivets will be just as hard. The web of some of the ribs is so close to the rivet hole, that you will most likely have to try and pull from the leading edge side. Trying to snake the puller into the leading edge and then to pull them with one hand will be a tough chore.
