I can't say I feel any of that..
A correctly hit loop does feel, er, loopy, I guess, and some blades feel crisper than others when hitting flat. Mainly, to me, blades differ in 1) weight (I really can't play with anything heavier than, say, 85g), 2) speed (that Yinhe N6 was WAAAAY too fast - I'd pop up pushes) and 3) vibrations. The one carbon blade I tried just FELT too hard (high pitched vibrations) and that Yinhe 896 vibrated in a way I felt was unpleasant. The Kiso 7 vibrated a little more than my old N11s but was otherwise very similar speed-wise, and was borderline too heavy (85g). The Darker was actually very light (73.4g) but it was quite a bit slower than the N11s. I should give it another try, that was an expensive blade, and I've since moved to the slower M8 - maybe it's the same. I got the Septear and the Darker because it was taking months for my first Kiso 7 to arrive - it had to be special ordered, and it was also quite expensive. The other two I bought when I visited Bandung, Indonesia (there were some for sale online).
