Seems as though Andrew is all about trying to steal everybody to CWF.
For beginners it depends on comfort level with writing. If you want to mirror a character and not have to think about a background or anything and pretty much just stick to typing words that they would say... then CWF would be the way to go despite it being more restrictive.
If you want more freedom in what you do, what you say, and the such... then WWS would be the way to go since there you can let your creativeness flow a lot more and not be restricted to performing a certain way.
But I will say for myself I started out in roleplaying feds and by doing that it made the crossover to trash talking a whole lot easier and very very successful. Also there is a better chance in longevity with roleplaying than with trashtalking but thats another discussion for another day.
But really... if you want a completely unbiased person to talk to about fedding... anybody from here on out hit me up. Yeah I'm in WWS but I've been in both style of fedding and have been inducted into a hall of fame for both styles and have bee very highly successful for both styles so I know the ins and outs, benefits, pros and cons of both. Because in the end it's about what would be most fun for you and... depending on what you really are looking for would determine what would work best.
