Washes are the subject I've been focusing on as of late. In my opinion, they are the lynchpin to trading successfully.
When you see the term wash, most people think "Enter a position. If it goes againts me, hold until it returns to break even and get out." At least, that's what I had in mind. But this type of thinking leaves too many loose ends - in the worst case it puts you in a position where you are against a fast moving market.
I think with washes, you use them just like all other components to trading this style. In other words
1. You know where you are
2. You know whats next
3. You know how fast things are changing
If you can't answer these three questions, you should be sidelined - not waiting for a wash opportunity.
If you can answer them, then you will know if washing is an option and if it's the optimal one.
As to reversals, Jack talks about using washes as practice for gaining skill with reversals - so it appears that you should be waiting on reversals.
Sorry if I'm over analyzing this - perhaps it is just as simple as the conventional wisdom. I have noticed though, that when I stop assuming I know what things are and start digging as to what they can be, I begin to think through a wholely alternate series of options.
