I don’t own an Area 51, but I did a report on www.mobiusflix.co.uk site a couple of years back. It’s a GREAT kite and a serious contender to the Minigem. A friend of mine later brought the said kite and we never have adjusted the bridle as yet, but we did play with some weight on the trailing edge of the spine (5 - 15g). This will help with fades, although its not very stable, but does "fruit roll ups" with ease (sometimes 2 or 3 rotations with one pump) but could do with some yo-yo stoppers. It backspins and tornado's like nothing else, slow or fast. If you like the lighter feel of the A51 then you'll love the Gemini, very forgiving but does give you bad habits as it tricks so easily. I can’t do everything with it but Andy Wardley certainly shows you it can. I am leaning towards the new bridle after buying a Gemini UL last year and will be converting one of my STD Gemini’s soon. Do you mean flick flacs or the flap jack, the gem & A51 flick flac easily if you give them plenty of slack and give a slight jar on the lines between accelerated pulls to dump air pressure at the end of each movement! The flap jack, now that’s another story better answered by another poster.
