So I recently bought a Model O and was very impressed with the mouse however ultimately unsatisfied as it felt quite uncomfortable to palm grip it with my hand size (20cm x 10cm).I have seen the Model D and have access to it but I'm not too keen on it as the trade offs in everything except the mouse shape in comparison to the EC2-B are not worth it to me, as I value mouse shape over buttons/cable etc.Cost is not an issue, as the Mamba will only cost me ~$20 aud more than the EC2-B.I'm unsure which to get, as I'm quite excited to try wireless and would enjoy the lack of cable however the shape is still very important to me as well.If I've answered my own question in here that's fine, I'm just looking to hear some opinions and ultimately try to be swayed one way or the other.Thanks!
EDIT: probably should mention that I'm an FPS player who is really seeking to perfect my play.
