It's probably best if we just chop the entire Mustache Wall and rebolt it in a 6'x6' grid. That way, no bolts will be too close together and routes can be described as a series of coordinates as you connect the dots up the rock. (ie. A1, B2, B3, C4, etc.)
if the bolt is 6' away you only have to go 2' above the previous bolt to clip it and then you're only pulling out 4' of rope so only a 6' fall max.
if you do them 4' apart you're looking at a 4' fall and you could hit the rock right at the previous bolt.
They should be 3' max for safety
