Just a few musings:
Re 1): Don't you think that losing top-end performance (for multi-rep sets) is an inevitable consequence if you stay away from failure training for a bit? I'm not sure it means much (if anything) as far as actual hypertrophy/size is concerned. How do you think it affects 1RM? I suspect that a 1RM resulting from a lot of failure training might well be a little higher than a 1RM resulting from a program where failure was mainly avoided (ie. like HST). However, I also suspect that you can get top-end performance back pretty quickly if you go back to more failure based training. That's been my experience anyway.
I also wonder if the technique of warming up to a heavier single than the working load could improve neural drive for the work sets because rate coding has been pushed higher for the single? (I don't think you've been doing this recently. Yay or nay?) This would seemingly prepare the neuromuscular system for higher output during a subsequent multi-rep set (making the work sets seem relatively 'light'). How effective it turns out to be might depend on how close to a 1RM the heavy single was. If it was too close to a 1RM attempt that might actually hurt a follow-up work-set because of a high amount of neural fatigue.
