I received both the A.G. Spalding & Bros. Maple Wood Beige Body and the Bullet Style from JetPens, and I have to say I am very impressed with the design and performance of these pens. They are perfectly balanced in my hand when writing, and the ink flows extremely smooth. The only quibble I have is that despite identical ink cartridges in both models, the one in the Bullet roller writes a slightly finer line with less to no feathering. That is just a minor gripe which I wouldn't have noticed if I wasn't comparing the two side by side. Overall, I am very happy with these pens and will be using them quite a bit.
