Spyder, by far if you want to do tournaments. The SF board was garbage, it had issues with some of it's programming (I believe predator code fixed it though I want to say, it's been a while) and the membrane was junk.
EDIT: Are you talking about the SF Trilogy (that still has a 3-way) or the add-on SF frame (that was just like an eblade but without anything resembling quality)?
