Hi Tami,
Most of us up here used the old style Roleez on our 18sqs.
The type with four wheels, one on each side of the hulls.
They can even be used without a connector section in the middle.
I know of one person who built an old-style set with the new style wheels.
The new wheels are larger and made of a different rubber/plastic which is much lighter and tougher.
They improve the design of the bearings also and the new type can be fitted to the old type wheels.
Back to the original question.
For single-handed use I like the Seitech design, configuration 15.
http://www.seitech.com/m/_general/Config15.aspI want to build a set with a similar design using the Roleez wheels.
