I have never used an overmold before but I decided to order an XT Nova to test out. So I got it today along with some other plastics and the first thing I noticed is that on the top where the 2 molds come together it is not seamless or smooth. There is a noticeable gap all the way around the top of the disc. Some places are smoother than others but overall it is pretty uneven all the way around. I also dont like the sleeves underneath the bottom where it is screwed together but I guess I can get past that. But gripping the top and there being a gap right where my thumb goes I am not sure I can deal with it. I was under the impression this would be smooth and flush. Is this normal or did I get a defective one?
