I am partial to the zenxten mount. No tools, centered behind the seat so you can kick your leg over, forgiving so your going to have a hard time breaking your whip. Did I mention you do not have to drill holes and I will send you a new mount if you find a way to break it! 
thanks for the shout out mmjsport and CDA I ride and the uniWhip is what I recommend.
