    There are some targets that look amazing in SHO (e.g., The Eagle, Heart/Soul, Rosette, Elephant Trunk, etc.). There are some targets that, in my opinion, tend to look a little weird in SHO (e.g., the Wizard, Bubble, Pacman, etc.). Then there’s M1 in a class of its own looking like a trippy, psychedelic party in space. I think my opinion of M1 in SHO was similar to how I first reacted when the Philadelphia Flyers introduced their new mascot “Gritty” – initially there was revulsion coupled with a ‘what is that thing!?’ that quickly evolved into a ‘holy crap – this thing is amazing!’ Still, I can understand if M1 in SHO is not your thing. Gritty though…
