In my experience you can still usually get 600-800 fpm out of the plane at those altitudes and weights with a high ISA if you keep your speed up. Your technique sounds like a good one.

Yeah, the book says not to exceed 15 degrees of bank at those altitudes and weights regardless of speed - So for me the biggest concern would be someone not knowing that, having the AP on in LNAV, and then comming to a big turn in their flightplan... Or getting a turn for spacing or something and not doing it in low bank.

I've seen different climb profiles,

The ones mentioned previously and;

There is the I've been Junior manned climb profile. (500fpm)

as well as the last leg of a four day profile. (mach .70 or greater.)

Um I think you mean the .80 and 270 kts (I mean 250 kts ehum) to the marker on day 4 right?

Save fuel days 1-3 so you can burn that **** on day four to make your commute!

The 'last leg home' .70 climb profile makes me laugh. All you end up doing is spending twice as much time NOT at maximum true airspeed. I was curious, so I held my tongue & watched one the other day -- ETE steadily grew by 3 minutes while FOB at DEST shrank by 300# .... and ATC ended up getting so tired of our climb we got a 'reroute for your climb' for the last 4000'.
