Ian, it's a good idea to come off that 1/4 throttle before commencing the run so you don't upset the god of gyroscopic forces! Is that what you meant but didn't write?
I too find Paramania wings are really helped by folding over the tips on a forward launch (personally I just pull the center of the wing back so it forms more of a V) because the manufacturer does not fit split A risers, which is a shame.
