Gonzo can be performed surrounded depending on object.
Pennies, dimes, nickels, (Are surrounded friendly) with practice!
If you just want to jump right in! (meaning with little to no practice) or your using a larger item *A battery (as seen in trailer) or the large bottle cap in the trailer. Then you have 180degrees angle coverage. Which is much better than straight on only angles.
Gonzo has the best angles of any sleeveless hold-out that doesn't use a wrist watch (and everyone knows in the back of their mind where it goes when they wear a watch)
You can perform Gonzo with sleeves up or down. You can wear a coat, or not.
