Questions about pad selection (B&S Euro foam)

Since my other thread was about comparing pads from different companies, I thought I'd make this one asking about the ones I actually ended up buying (Buff & Shine EURO foam 6" pads.)

Anyone familiar with these B&S EURO foam pads at all (not the uro-tec)?! I bought yellow (heavy compounding), orange (mid cut) and white (polishing) for this project (my 2014 Chrysler 300C) to try with the supply of Meguiars Ultimate line compound and polish I have lots of right now. The yellow pads don't seem to feel much different then the orange EURO foam ones I got, but I'm still trying to decide if the yellow Euro foam pads will be to harsh with Meguairs UC?

There are some bad marks on my 300 from the previous owner (looks like it was only washed in a brush wash car wash, maybe a wire brush too, lol, its whole life :( )

Thanks for the help all!

Yellow or Orange pads seem very similar to me with the Ultimate Compound. Though in my learning I was overdoing the amount of UC on them initially and over working the pads a bit too. I wonder if I should have gotten finer pads then the whites as well, but they seem to be doing fine with the Ultimate Polish. I've been able to get rid of many of the door scuffs and minor scratches here and there on my car so far, and though I've run into an issue with the paint on the one side the car is looking much much better!
