Strongest suggestion at a lesser dollars is the wheel pants by
www.speedpants.com. Located at Daytona Beach. The very same company that has
done laminar flow systems and power flow systems.

You'll be quite happy with the 9.12 knot increase from no wheel pants, and a
6.95 increase over the old style Piper wheel pants.

Well, from their own desciption, it looks like the difference between
'78 style Piper pants (what he would get with item #2449226814) and
the Speed Pants is only 3mph ?
