Well it is good to see this being discussed so that you are all ready for next year, (got my scrutineers hat on now
)
Just wanted to add my 2 cent's worth, there has been a mention of the battery systems, if im honest I much prefer the cable sort. They are less prone to failing. I have seen a lot of battery ones not work, or go off by accident and you have to remember to switch them on and also to replace the battery.
As racing59 said, make sure you keep looking at motorsport now, there is a big section in the latest edition pointing out a lot of the new changes, and also read this years blue book as they do point out changes for this year and very importantly make sure you read the 2006 book when you get it and dont just throw it in the corner of the room and forget about it.
Oh and one other point, if you are putting in your plumbed in version for the first time dont forget to put your stickers on
