This kind of question never has a set answer. Generally speaking if you have more than enough craftsmanship, control, and cp, just SH2 and 100 percent your touches with basic, standard, or advanced touches than finish with gear strides, ing (ing2 for 2 stars), innov, byregots and standard synthesis or careful synthesis 2 until finish.

Hasty touch is a fantastic skill and people are right that generally speaking hasty touch and sh2 will cost you significantly less cp in the long run. If I am using all normal quality mats for a 2 star item, then yea I will go hasty touch method. For 40 dur 2 stars it works 70 percent and more of the time. For 2 star 80 durabilities with all normal mats, I use everything and go with the final combo at the end and it hqs guaranteed.
