Yeah, if 110 gets you to where you're happy then that's great.I used to use 205 but when it didn't clean as effectively on some more blemished or weathered paint, I tried 110. That worked much quicker and better and I couldn't tell the end result from 205, so I've use 110 as the only polish before waxing. If I get a 2 or 3 year old car with clean paint I may use 205, but for most, it's 110 and it still looks excellent.
If you have more soft paint then finishing with 205 has more benefit.
