Crimson Fists and Power Fists

[Pooky]

Is there any fluff that says Crimson Fists are more inclined to use Power Fists as part of their war-gear than other Space Marine chapters?

The reason why I ask is that Pedro Kantor and Captain Cortez both use Power Fists as part of their war-gear. Admittedly, that is only 2 characters but we do not see many others armed with Power Fists.

Since Fist is in the name of the chapter I imagine powerfists are more common in the chapter than others with a less fisty name.

However being Imperial Fist successors they should also be fairly skilled bladesmen, since they would be partaking in the Feast of Blades competition.
