Their size makes it easier to install on larger gauge wire.

I'm not changing anything I've already got set-up. I just figured the next time I need to buy some for future projects, then I'd go with the larger ones for ease of use. It's annoying to cram 10-12 gauge wire into the 30A contacts.

Also, I don't crimp mine. I solder them. PP's are much easier to solder than Dean's and TRX in my experience.

Hmmm, soldering huh?

So would 30A casings with 45A metal contacts be okay, for a high-end setup?
Say a MMM 2200kV on 6S?

As an example..

I don't want these to melt out on me if I'm gonna be spending money on em! :D

I've been using the smaller 30A metal contacts on a MMM/Neu 1515 1y/6s for a very long time now, and they don't even get above ambient temperature .. not even when geared to the moon for 70mph speed runs.

Believe me, these PP's are very much up to the task.

Sweet....
Looking forward to pickin em up.
