Apeks xtx50 2nd stage/octo

[Shark Bait!]

Is there any difference between the Apeks xtx50 second stage and the octopus version other then the yellow color? I want to use this as my alternate/octopus and wanted to know the main differences and the opinions of others that have used this particular regulator.

Oh i dive mostly warm water.. S. Florida/Caribbean

The only difference between the 20, 40 and 50 is the cold water radiator on the 40 and the cracking adjustment knob and cold water radiator on the 50.
