Agreed, that's how I started but times change and it will always be for me a multi-skilled trade, you should be able to handle tube when required but equally you need the daft wee code at the end of your card that allows you to erect system as well.
The system training still confuses me, with us having to do 2 day's in our system of choice that allows us to build from 1 manufacturer only, yet there are still lots of 3 day courses that allow muppets to erect anything they like. I know it's boring and I know I have posted this before but until I get my head around it this will always confuse and annoy me.
