Well, a few of the guys on my team play with RT's. I personaly hate them, and it's like ciaran says, they chop alot of paint and mess stuff up with that mode. However, if you remove that funktion your RT will be just like a .68 mag anyway! I talked to a guy that arranges tournaments the other day, and he said RT's will be banned from tournaments with millenium regulations soon. Don't know for sure if its true though.
peace
