Dear Billy,
it's not something I use daily but I have the LC Hybrid Wool pad and that'll cut cut cut like there's no tomorrow.
It fits great on standard backing plate.
I like to pair it with Menzerna FG400, honestly I never tried this wool pad with meg's 105 or 100 that I have here, either for lack of time for extensive testing and because it worked so nice and finished well using FG400 (the first I was able to test with).. Generally I tend to stick with what works for me.
For general use, when still need cutting but not that crazy of wool, I'm using Hybrid Orange pad paired with the same FG400, and this setup finish up LSP ready many times.
Although it may work on hard paints, I've faced once a hard, hard, hard paint that orange + Fg400 struggled to correct, I mean, needed much more passes and slower arm speed, more pressure than conventional hard paints, so I was dealing on the danger side increasing too much heat.
If it's just a bit hard, maybe orange will do the trick, but harder harder you'll benefit from wool if heavy and fast cutting is needed.
Sincerely, I just use those ultra cutting combinations in extreme cases, spot correction or to remove sanding marks.
I'm more liberal with orange, but like I'm mostly refinishing, white hybrid is about what I most use.
I also like MF pads for cutting harder, but I was not able to use properly with my 3401 yet.
That's because I have 5.5" MF from my 'old' Meguiar's DA, but only 4", 5.5" and 6" plates for the Flex... I have tons of MF discs, cutting and finishing!, that's why I've not ordered more MF in 6" for the flex. I've decided to order smaller plate.
Because I like them too much, I've tried on 4" plate (not optimal, but could test), and on 5.5" plate, very dangerous to use this way with MF risking to scratch the backing plate on the paint (although I may use foam pads matching plate size sometimes, they have more 'complacency').
So I've ordered 4 3/8 flex plate at AG, it's in my order to come next week. Can't wait to receive (many goodies! lol), but also the plate to resurrect my MF and keep using them often as I would like.
On the other side, I'm able to use my 4" MF discs (from LC, DA version) / 4" LC flex plate for spots with great cutting capability.
Let me know if you need some more info,
Kind Regards.
