So I was registering yesterday, and when it comes to picking discs there are two options for each specific disc, and weight: Lace 160-169 XLM or Lace 160-169 XLF. Not being a regular vibram thrower, my question is what does the XLM/XLF stand for? Are they different plastics/rubbers? Thanks Mar 11, 2014
