Nickname for Israel?

I have always loved the name [name]Israel[/name] for a boy. Not only is it a family name, but I love the meaning “to struggle/wrestle with G-d.” I don’t, however, love the nickname [name]Izzy[/name] or Iz for a boy. My grandfather [name]Israel[/name]'s nickname was totally unrelated to his given name, and so that doesn’t give me any good places to begin. What do you think might be some nice nicknames for [name]Israel[/name]?

[name]Ray[/name] or [name]Rae[/name] fit as they are shortened forms.

[name]Rae[/name] or [name]Elly[/name]

[name]Ray[/name]/[name]Rae[/name] is definately the most prominent nickname…
[name]Izzie[/name]… but I dunno how thatd fly for a boy…
