best self-launcher propulsion system?

Guys

Many thanks for your thoughtful comments and insight. I had read most
of the literature of every type of self-launcher and touring
motorglider, but your first hand experience is what i needed to hear
about. Clearly there are substantial tradeoffs and advantages and
disadvantages for every type of motorglider (not even considering
cost!). I will keep monitoring manufacturing developments, especially
for less expensive electrics. Unfortunately i am too tall (6'4") for
the Silent electric (assuming the cockpit is the same size as the
Silent petrol).
