I had a look at my options after a fantastic tasting in stag's leap so may not be firing on all cyclinders.

I have reviewed this as my best option http://www.insurance4carhire.com/usa-canada-car-hire-excess-insurance
It looks likes it will cover everything that I need and has CDW & SLI

What do you guys think?

I don't have a Amex as I found that nowhere took it so was little benefit but after the info above I might re apply.
