1) Based on my own + others' past experience, a skewed distribution toward the right (7 being left, 8 being middle, 9 being right) had been observed, meaning that landing +7-8 had occurred more frequently than landing a +9. There's no definitive means, however, to substantiate the idea that this observation matches the actual scroll distribution.
2) Is gaining a few more M.ATT worth the cost of spending extra nx on protection scrolls, guardian scrolls (if you don't have an ample supply of the booming 25%'s), and/or return scrolls (in the event you land a +7)? From a cost-to-benefit analysis, I would say it's wiser to go with the RED 50% +8 att scrolls.
