Kryogen:
1. try re reading my post again. it is not that complicated. I am talking about how your sequence of operations has redundant operations and offering a better method.
2. You are trying to figure all this out without the benefit of having a machine in front of you to help you understand the operation. Therefore it appears to be too complicated.
Sorry I need one more line.
3. This is the exact reason why you need to drop back your expectations to a 550B. The 650 and 1050 are exponentially more complicated than a 550. You need to learn to walk before you can run.
