Congratulations,David! Welcome to the Club of Agraffe Wrestlers! As my teacher said:It's NOT as complicated as it looks,Its' even MORE SO!but it's duable,especially,if you have all the right tools.The kit you had assembled is a must in the field,it helped me many times.Often clients will tell over the phone that keys are sticky,Hammer is 'HANGING BETWEEN THE STRINGS",brocken strings,etc,and all it is is another "ROOT Canal" job . Regarding difference in sound-tonal qualities:no questions,clean agraffe holes reduce need to use voicing needles besides the appearance and safety not to deal with the brocken ones in the nearest future. I'm still very suspicious and sceptical about using the "Lock-tight".I had special plugs made from brass,1/2" dia with pre-drilled-pre-tapped holes for 7/32" and 1/4" agraffes and it works,helped a few collegues when the threads were badly damaged.And from the top nobody could tell where repair was done.In Kansas city I'll show those plugs to Herb and Bob Marinelli,maybe they can manufacture them,it's very simple idea. See youy in Kansas City , Best Regards..
