Again, you have no idea if that is true. Max cog size is not the typical wisdom that gets passed around here. It can be lower or higher than the stated max cog size for that derailleur depending on the exact frame and hanger.

Would I get noticable lower gear with a 12-32 or 12-32 spread; and 2. What are good cassette choices - Shimano, Shram, anyone else?
Thanks.
If your bike is already shimano equipped keep the cassette shimano. And if you're going to go to 12-32 you'll very likely need a new derailleur as well in addition to chain.
