Meguiar's Microfiber discs

[Nutbolt]

hey all,
I am currently using and loving the results I am getting with the megs microfiber correction system. I have used it as intended and modified a few times with a process like d300 w/ cutting disc, then d302 on finishing disc, then m7 on foam , then m21 on foam. Anyways to my point, how many guys have used and found the extra cut discs helpful for deeper scratches?
When are they useful compared to the cutting discs? etc..
thanks

I have not used the extra cutting discs yet, but a cutting disc with M105can take out some pretty deep scratches.

While i haven't yet used m105, just d300 and UC for cutting, i have read great stuff about it. Does it have enough cut over d300 to be worth having both in your opinion?

Go on you tube and search for Gary Dean. He did a comparison betweeen d300 105old version 105 new version and 101
