i think the lines looks better as with the sidewinder - more smooth and its hurts less tell me the clients. I have a new sidewinder v3s with the new springs to use the sidewinder with 5.5v and its works very nice too. I dont have now any splitting issue and really less trauma on the skin. The mojo works with carts but i think its loosing power with carts or slowing down. Dan are amazing with normal needles
