Fletch2468 I understand you wanting something like that, I have a tattoo of the Tazmanian Devil but I got that while I was still out there, looking back at when I got it that was my alter ego.
My father gave some very sage advice when it came to a tattoo, first he told me that no matter what I got or where it would be forever so be darn sure of what you are getting, he said to always keep in mind that one day I will have grandchildren and to make darn sure it is something that if they ask about it it will not be embarassing.
I am not sure what type of work you do now or what you do in the future, but a tat on your wrist is not always looked upon with favor by a possible employeer or by prospective clients.
Think long and hard about where you may be 10-20 years from now. If you decide to get it give real serious consideration to where you get it.
