Hello,
I'm not sure if you're still looking, but if you are, you could try giving my app
RSS Central a try -- I think it does the things you are looking for.
It's a stand-alone reader, which isn't integrated with Google at all. It supports import and export of .opml files (using Dropbox to transfer the files) and this makes it a piece of cake to synchronise the feeds you are using between Outlook and the phone. You can export the subscriptions from the phone and then import them into Outlook by right-clicking the "RSS Feeds" item in the tree and selecting "Import an OPML file", or alternatively export the feeds from Outlook into the appropriate Dropbox folder and import them into the phone. I'll be happy to provide more details if you need.
The scrolling is smooth too.

Give it a try and let me know what you think.
Best regards,
Adam.
