So I always struggle with which I prefer. 
 
Trades make it so incredibly easy to read the story and get the info you need... but there is just something so awesome about having the whole set in single issues. It's almost like completing a puzzle when you have them all. 
 
Does liking one or the other really say something about a personality. Am I super materialistic because I like to have the individual issues? Am I lazy and/or cheap because I want to get books in trades? 
 
The advantage to single issues... it's maybe 25 pages (post ads) and you're done with that issue... .you can continue later if you want.... with a trade it's all right there... easy to lose yourself... both have a good side and a bad side.... I think this is something that will forever plague me... 
 
Though thinking about it... I have a comic box at my local comic shop, they have my card on file and will automatically pull the weekly books I want and keep them aside so I can pick them up later and not miss anything.. with a system like that I am almost always going to have the single issues.... so perhaps its environmental... maybe people with easier access to a comic shop are more prone to by individual issues and people who don't are just so satisfied to read anything they go for the trade.... interesting theories floating about here.....
