You could better it (aside from the insurance) by pairing a Business Platinum with Business Blue Plus. Business Platinum gives you $0.0154 for Pay with Points airline tickets, and Business Blue Plus gives you two points per dollar on all spending, capped at $50,000/year.
That's fair - and for me the 1.5 CPP on Chase is just a fallback, I typically have been able to redeem for much more through transfer partners.
I do see the benefit of the AMEX Business ecosystem but at least at this point in time I remain wary of going down the business card route since at present my "business" is limited to a couple eBay/Amazon sales a year.
