I also agree with SASless, but note the above. Would it not be possible to arrange with the airfield operator and/or other operators to facilitate a climbout with an early climb-out turn to keep you closer to terra firma?
Failing that,
dietlhelm's 270 auto would be my preference. From 700 feet you should have enough height to do that. We used to do 360 autos from 1000 feet in the Bell 47.
