Sheiko questions

I decided to start playing with the routine at http://www.zyworld.com/powerlifting/ sheikotraining1.htm, but I've a few questions:

What are 'Squats 'Scissors?'' Lunges?

Is there a critical difference between his 'Good Morning' and an SLDL? Or does he mean the 'yes/no' style 'Good Morning?'

How long between sets? At forty sets, I could be in the damn gym forever if I'm supposed to wait longer than 60-90 seconds between. And unfortunately, the alternative is to cut some stuff out of the routine, which I'd rather not do.

And has anyone ever tried alternating a straight PL routine like this with an OL routine, say 2 months of one and 2 months of the other, in order to maintain speed? Any suggestions for how to do that?

Have you found that you need to cut sets out of the 'official' Sheiko routine in order to add speed work and still avoid overtraining?

Also, is there an overtraining issue in following Sheiko and running on the off days? Or at least, have you had a problem with that?
