Re: lowering BIG blocks. Whats your crew like? Taking down big blocks rigging off the stem relies on the abilities of more than just the climber, you need experienced ground crew, and of course the right gear.
For the job you describe I would want at least 3/4 static line a block and a porty, with those basic elements and confidence in the groundies it should go well, physically wearing but manageable.
Pace yourself (if you're the climber ensure you have 2 tips its less strain on your body as much as anything else) trying to turn a 4hr job into a 3hr job can often result in 6hrs of struggle and exhaustion.
