I would take whichever is better for your at this point, ttokkyo is more established but I would hold off only on the cyp200 until the fixed batches are in circulation (in some areas i hear they are already selling). I havent heard anything negative about QV from the product side _so far_ so that seems to be in order, their paperwork may be alittle skewed right now. For me Id still go with ttokkyo, but the price differences arent too great at all in favor of QV.
