Help with a Spell, Looking for balance Options

[jmecha]

A player in our group wants a spell for personal flight so his Combat Mage can fly around faster and with more manuverablity then the core book's Levitate Spell allows. basiclly the Combat Mage wants to create a spell that lifts less wieght per net hit in exchange for increased speed and manuverablity.

I would like to see what examples Dumpshockers can toss out here, to get an idea of what a flight spell would look like at other SR Tables out there.
