I dive a Hollis M1 Low volume, Black, silicone skirt frame-less great fit. I have in my collection a Scubapro, Mares Liquid Skin, Hollis M2 and last but not least, a Sherwood. The soft nose allows for one handed equalization. I have never tried a colored lens. So no comment there. No purge on mine I’ve never needed that feature or felt that it was worth the extra bucks. I can clear and equalize quite nicely with the Hollis. Cost for one from Scubatoys is about $80.00 or so. Hope that is of some help
