After all this I ended up trying on both the Grillz and Profilers at this weekends CPPS. The Grillz fit me really nicely but I wasnt a fan of the hard ears nor the foam, the profilers however seemed to push really tight on my ears, again with them being hard I wasn't a fan.... ended up buying a set of Purple Vios and they're great! Feel like i4's in their weight but with an even bigger field of view and better coverage of your forehead/chin. Only problem is they are on the expensive side!
But thank you all very much for your advice, it's been much appreciated!
