|Jay, I am a little confused from your post. Are you saying they are discontinuing the Super X plates? Also, you mention that you need to buy the 4" trucks to fit the plates. I have a feeling I misunderstood you. I am guessing they come with the small trucks, but you can put the wider trucks on? I use wider trucks on mine and I thought you did as well. Also, if you end up using the Super X plates instead of a custom set up, then I highly recommend Rollergirl's new slide bar. I am not much of a slider, but love them for plate stahls. You would kill on these things.
