Actually, I don't see plasmatech used all that much. It really deserves more than what people give it credit for. Maybe it's just me, but I really like the blue colour scheme, and some personal colours look especially good with it. I remember wearing it a lot around the time it was released, especially in Blast Network (you know, those days when there were no Lockdown?)

My final word would be, use whatever you like. As long as you think it looks good, you're game, and nobody has a right to trample on your opinion. That's why it's called 'an opinion.'
