TM flat out, battery size is up to you, full size in a full stock, mini only in a retractable stock version (in the foregrip, although there are aftermarket foregrips you can add that will take a large battery, and mount anything you like on it including turn signal lights). SD would be good for your tracer unit, but also keeps you at the 229mm inner barrel length. if you never use a tracer unit, you can install a 330mm inner barrel and get 20fps higher velocity.
And, apologizing for your english is not required, there are guys on here that have english only as their language, and totally bugger up the typing, all the way to a 300 word post with no capital letters or punctuation, and sound like retards by the way they type.
In other words "U dun gud!"
