Best Filter for Shooting IR with 60D

Doughboy

Does anybody here have any experience shooting IR with the 60D? I understand different manufacturers and different cameras have different IR blocking filters. This is my first foray into the world of DSLR, but I enjoyed shooting 35mm IR film back in the day. I'm hoping that I don't have to buy 10-15 filters to find out which one, if any, will work the best. I have the 18-135mm and 70-300mm IS USM. Any advice? Thanks!
