The first pitch of Shake N Bake is a worthy candidate for new bolts. Would compliment the excellent new bolts higher up on the route!
Also, a new bolt or two on Heat Seeking Moisture Missile would make the lead a slightly better idea. I think there's a new bolt on that one somewhere higher up.
Not sure what the story is on Shake and Bake since it is listed as '76 and not on my master list on p3 this thread.
Rubine listed them as 3/8" split shaft. S&B has quite the classic history, so I personally wouldn't touch it without one of the rebolting masters along to help.
Maybe Bruce or someone else can shed light on how there can be new bolts up high but with no record I can find either on here, ASCA, Clint's page or FOP. I have been on some of the other old Higgins routes and the star drives on those are still in good shape. Just a suggestion - It would be helpful to know the specific condition of any routes suggested for rebolt - bolt type, hanger type, tight/loose, rusted - etc. I try to take notes and pics when I lead up something that I think is a candidate.
Moisture Missile is Jim's route and he is still an active climber, so maybe he'll shed some light on the nature of the hardware on that route. It is listed as '84 so it's much newer than many of the other older routes still needing attention. Rubine has 1/4" and 3/8" split shaft.
