I bought myself the Dye i3 Pros. I'm now using the Dye i4's because I wanted something a bit closer to the face. Love the fit of the i4's better. Also the lens is far easier to change whenever I need to.
Personally I use dyeI4's because they fit my face well however it really depends o. your head size and other details such as colour preference and willingness to be shot in comparison to desired airflow.
However I have heard of people installing inmask fans
I went for the Empire Helix as my first mask and couldn't fault it, apart from maybe the foam being a bit hard. It pales in comparison to my E Flexes. I'd recommend picking those up if you can afford it for a first mask. Comfy as hell and no worries about difficulty breathing or fogging.
