Gonna keep a roo or two, but which breed?

We have chicks (straight run) in the brooder right now. We would like to keep a rooster (2 preferably) and the rest of the roos will become dinner. The chicks will eventually be introduced to our current flock of 6 hens (3 BRs and 3 EEs) when they are old enough. One of my concerns is size, but DH says it is not a big deal . He really likes the BJGs, but I am concerned that the roo would hurt my small EE, Pia. Pia is a standard, but she's only about 4.5 - 5 lbs (though she is tall and slender). She's a bitty for a potentially 13 lbs roo, right? We also do not want a roo that is of a breed that's known for being obnoxious and/or aggressive. Of the following breeds, what do ya'll recommend? If it makes any difference, our chicks are from Privett (via Welp). Thanks!

The chicks are a mix of the following breeds:
mottled Javas
Buckeyes
black Jersey Giants
Delawares
salmon Faverolles

 

I know roos like to be heard, so for it to be considered LOUD is frightening! Mean on top of it!

Why the breeds in that order? I have read some on Buckeye, Jersey Giant and Faverolle roos, but haven't found much on Java roos.

Why an Ameraucana roo? Are you referring to the purebred or the EEs?

 

Anyone else? I appreciate your opinions since I don't experience with roos whatsoever. Thanks!

 

I think the salmon faverolle roos are the most beautiful rooster! I didn't know they are gentle too! Are they good protectors of the hens or are they too gentle?
