That's right! The main difference between the performance and basic flukes (besides having or not having a layer of neoprene) is that the performance fluke is molded and the basic fluke is textured (no molding involved, just texturing of the silicone). Therefore the basic fluke can be customized a lot easier, and for no additional cost. But you have to specify to her what fluke shape you want when you order, and what she can do with the texturing process for the actual texture (not shape) of the fluke is limited. Otherwise to customize the performance fluke there is an additional cost, as she needs to sculpt and make a whole new mold for you.
