"Buff fan-art" TMNT - Which turtle? (Patreon)

Those who follow me for a while know that I sometimes do buff fan-art of fictional character from the popular culture (games, TV shows, cartoons, ...).

It's been a while I haven't done one and I would like to draw a Teenage Mutant Ninja Turtle, but which one? 

I could have made alternative versions with the 4 colors, but I want something more interesting: each turtle holds a different item related to their muscle grow, which one do you prefer?
