Shower Guest List Question

Hello Ladies,

Lurker here with a question...

I am carrying twins and my shower is scheduled for March 2 based on the advice from the MoMs on the multiples board that an early shower is a good thing when carrying multiples.  So, I am putting together the guest list for the hosts and am wondering what to do regarding a certain group of women that I am not particularly close with, but whose husbands are all like brothers to me.

We aren't that close these days b/c most of us have moved away and seperated, but I grew up with these guys and invited them to my wedding/were invited to theirs (as a guest of the groom).  However, as for their wives, I can only say that I talk to only two of them and it is still a bit strained and none of them invited me to their baby/bridal showers. 

I am thinking of inviting the two that I am more friendly with and leaving the others off the list, although I would love it if all of their husbands came (although I am not sure if the hosts are planning a co-ed shower or not). But, I don't want to be rude by invited some and not all. 

What should I do?

TIA

ETA: the shower is going to be in my hometown where most of them live and they are close with one another...
