Yes, I would use 6 between the breaker and the terminal block in your control panel.
I really like these blocks and have used them in several panels:http://www.elecdirect.com/product/66...7ea6ffdbd.aspx
You can run your 6 in and tap off to your fusing. They work nice. I usually put in four for the hots, neutral and ground.
