Cutting in a system isn't quite the same as cutting normal growing hair. This is especially true when it comes to blending. A good stylist that has spent years cutting in systems knows the little tricks and idiosyncrasies of it. Sure there are people here who've had great cut in done by regular stylists and even themselves. For awhile a lot of guys were using Flowbes with great results. But in the end a good stylist who's experienced with systems ids going to have much better skills than i do. I have a trendy, choppy haircut that i just can't produce myself. With a piece you have one chance to get it right because that's the cut you're going to wear for 3-6 months. And if they mess up your piece then that's on them not you. For me it's worth the extra money to have a professional cut my piece.
