I would get about 10 or so. and 5 of the PC crush washers. The 22mm x 1 shimano crank puller worked like a champ. You want ATLEAST a 5lb slide hammer. I will have the tool for the collar for rent. I will charge $5 per loan + shipping and just take it out of the deposit. You can try making your own using a 15/16th socket but I was never able to get enough torque this way.
