Been sitting on this info for a while.... ask me how I got it I love stroking my ego and bragging. The juicy bit: Head hitbox volumes And the slightly less juicy bit: Total volume of all hitboxes on a model. Keep in mind this can be skewed due to overlapping hitboxes and the fact that some models will have extra details that others don't such as finger hitboxes.
From what I'm seeing it looks like Harley Quinn is one of the best skin options. 3rd smallest total hitbox and the smallest head hitbox out of the top 6 totals. Yennefer would also be a really damn good option. Either way, im sticking to my Triss skin. This is actually really interesting, so I'll bite. How'd you get these numbers?
@Xerp asked about default models, the phoenix, leet, and guerilla all have the same sizes: models/player/leet.mdl 617.5 models/player/leet.mdl 9976.7100816548 models/player/guerilla.mdl 617.5 models/player/guerilla.mdl 9976.7100816548 models/player/phoenix.mdl 617.5 models/player/phoenix.mdl 9976.7100816548
