Ab,
Those sound like good choices for a Hammer arsenal. Everything I've heard and read on the Big Deal is that the flip block and the Cut-Throat coverstock really match with the Gas Mask core. Judging by the numbers, you'll get a similar roll as the Blade Reactive with more performance in heavy oil. The Real Deal will roll sooner and give a great strong arc. So it's a toss-up unless you're a cranker and then I recommend the Real Deal. I you stroke it more, then go Big Deal.
The Sling Blade is a darn good ball for medium to light oil.
Sounds like a sound strategy.
