The shape of the Light² 180 is best described as a slightly bigger and bulkier Zowie S2. Much like the latter, the hump is placed more towards the back, sloping down organically towards both ends with the back flaring out more than the front and the sides curving inwards. The HK Gaming Naos-M is a more faithful recreation of the original S2 (euphemistically speaking), whereas the Light² 180 feels slightly different in hand, albeit still easily recognizable as an S2. Despite the Light² 180 hardly weighing more than the Naos-M, holes as a weight-reduction measure barely see any use. In fact, when using the solid back cover, the Light² 180 doesn't have any. Overall, a tried and tested shape that works well in practice.
As for grip styles, I'd say the Light² 180 mostly suits claw and fingertip grip. It's a medium-sized mouse with a moderately pronounced hump, which should make it generally suit most hand sizes. For reference, my hands are 19 cm long and 10 cm wide, and I found the Light² 180 very comfortable in claw grip.
