In my experience, the mileage upgrade is tough on the 752 in either direction because there are so few seats (and that was as a Platinum). I'm not sure of the exact number, but I'm probably <20% on mileage upgrades to Europe on a 752. On the 777/764....almost 100% on BF marketed flights.
No- I booked B because it was only $200 more than standard "H" and less than the $400 upgrade fee. I won't burn miles on the outbound, only the return.
