To change or not to change....
Wiz...
The repair guy, doesn't look much like a Wiz and tho cute, I don't think it reflects you. The second Wiz is very similar to the original and in fact you could use both.
For example...When you are demonstrating or giving an answer to a question, use the 2nd Wiz. Then people will know you've worked "your magic"...again.
The Original Wiz is good for printed material where "web action"can't be seen.
