No cheaters needed. Probably the most popular floating tip to use to make a floating Skagit head, is to use a Rio Mow floating tip. A 10' medium Rio Mow floating tip (450 to 575 Skagits) would be appropriate for your Skagit heads.

Airflo has recently come out with the new Rage floating Skagit head, which is quickly becoming the preferred floating Skagit head, versus adding a floating tip to a regular Skagit head.
