Yes I did a split batch, and about 10 AHB people tasted them side by side. As I recall nearly everyone was able to distinguish between 1056 and 1272 in a blind tasting, based on fruitiness, but opinions differed over which was the best. But, in that case the 1272 batch finished 2 points higher, and those that preferred the 1056 pointed out the lack of residual sweetness. So personally, I prefer 1272 now, which definitely accentuates hop fruitiness, but only if you pay attention to yeast health and get good attenuation.
