What are the odds of Google putting a parked domain in the google dungeon where they like to put MFA sites and such ? Will it be possible to rectify that once the domain is unparked and good content put in ?
If you redirect the domain, then the parked content isn't even on your domain. You basically arent really building any kudos (or loosing any) For example I redirect http://www.youlist.co.uk/ to sedo.... check it out As for Dungeon... Google provide most of the advertising for these parking sites, so they obviously dont mind them! As long as the content is not offensive, you will be fine. Google won't like it if you send lots of rubbish traffic though. Actually, they won't like it if you send any traffic. They want parked domains with natural traffic from old links or type in errors. They aren't too keen if you experiment with sending adwords traffic to adsense sites. (Risky financial gamble anyway). Good Luck.
someboday said parking with sedo.com is a good place to get some revenue. maybe you should give it a try.
Most single page parked pages will not rank well in the Google search engine for competitive terms. Sites would need to have authority to rank well and that is hard to accomplish with one page.
