I had some Griot's 3" red wax pads tear like that and it was from what Mike said, the complete back of the pad wasn't covered in Velcro and the BP tore into them - but those pads are extremely soft. The solution is just to get some different pads. Oddly enough, I use the LC CCS Cool wave pads, and the backs of those are like the Hybrid pads, but I haven't had this issue with those.
CCS and Hydrotech pads work good with a Griots in both 5.5" and 6.5". The backing plates I use with those sizes are 5.5" Euro BP from Pak Shak (~5") and with 6.5" pads I use the BP that came with the Griots machine. I also use the 3" and 3.5" LC BPs with their 3" and 4" CCS pads without issue.
