Remember that if you don't like the look of the Ares 2, Innokin are bringing out an LE versions ( soon? ) which removes a lot of the branding & gives the rta a 'plainer' look.
Only have 3 or maybe 4 MTL RTA's but from that 4 i think i rate the Pandora the best but in no way shape or form do i pretend to be an expert when it comes to MTL.
