Um.. I think Hollowtech is a type of crankarm design and the octalink is the Shimano version of how the crank arm is connected to the bb. So they aren't related in that way. I'm pretty sure they make Octalink Hollowtech cranks.

For example, older XTR cranks are hollowtech design with an octalink interface and so are the black shimano 105 road cranks.

The only thing hollowtech means is the crankarms are hollow. Octalink is shimano's spline design for bottom bracket spindles on their non-external bottom brackets.

Hollowtech II is an advance in the hollowtech technology to accommodate an integrated spindle which goes through an external bottom bracket. So when you hear hollowtech II, it's external and Hollowtech internal bottom bracket.

Sorry but Hollowtech is a method of forging crank arms that was invented by Shimano. The arm itself is truly hollow (I've seen one cut in two). It does make the arm lighter than a normally forged unit.

The rest of your post is quite correct.

Hollowtech - cheap, lightweight, one size fits all bottom bracket, shorter life, can be easily kill (no direct connection between the two bearings)

Octalink - heavy, multi size needed, last longer

Someone has no clue. Hollowtech cranks are pretty dang strong.
