Hey yall,

First off, long time reader but first time posting, so thanks for all the valuable insight that everyone has provided in helping me make big decisions as I'm hopefully moving up to a regional soon... but still i'm a newb so please go easy on me.

I had a quick question I wasn't able to find much info on.
Quick rundown:

Sending in my app soon and my goal is to eventually hold IAH in the CRJ. Does the seat lock apply to the CRJ series as a whole or specifically a 200/700/900 as well? Will i get trained in more than one or will I only fly one series (I noticed pay is different in some cases). Also, I've been trying to find more information about how to decide between each a/c with fleet size @ IAH, routes, number of flights, etc... as it seems that this could very much affect QOL and schedule when bidding.

Any input is greatly appreciated.

Again, if this question needs to be clarified, is generally a dumb question, or if I missed the answer somewhere in the depths of the search function, feel free to let me know. Thanks in advance.
