Best homebuilt for ~700 nm commute

While the RV series and many Composite designs are great, don'g
overlook the W-10 Tailwind.

I believe an O-320 powered one has beaten many RV's of higher power in
the recent OSH races. Using an O-200 or O-235, they are almost as
fast....just don't climb as well in the Rockies. Which you don't need
on your route.

Construction is about as straight forward as you can get and very
economical. Modifications by Jim Clement have really improved the
first "approved" two seat homebuilt. And there is a tri-gear version.
