I'm about to mount a pair of HH's and I've got a question. It's my first time mounting a binding and I want to know why the 22 designs has two different options on the size of bit to use when drilling. They say it's up to the manufacturer of the ski, but I always thought the size of a drilled hole accepting a screw was determined by the size of screw that was going to be used... The two options are a 9/64" bit and 5/32" bit. Which should I use? I'm thinking the 9/64", but just thought I'd ask before 'bitting the bit' so to speak.

The rest of 22designs instructions are great, but the bit size has confused me.

Bit size will depend on the ski: *Use a 5/32" (4.1mm) bit for those skis with metal top sheets. *Otherwise use a 9/64" (3.5mm) drill bit.
