From what I personally experienced when testing both in my buddy's EZ98 (with one Wilson Pro over grip and 1g of lead @ 10 and 2 each), I thought both M8 and DF played better than Tour Sniper, but to Sniper's credit, it was one of our first tests, and I think we strung it too high, something like 52/50, when we probably should have strung it in the upper 40's, at the most. So the fact that it felt a little too boardy and harsh probably came down to too high a tension, more so than the string itself. Given a re-do, I think it would be a much more even result, probably closer to DuraFluxx in overall performance.
