Great explanation. I love the ball pocketing feel of M8 as soon as it breaks in. 42lbs is my sweet spot where there is perfect control and a ton of power and spin due to snapback. Honestly, it it my favorite string ever- even more so than gut/poly hybrids. Better control, more spin, and comparable power.They are both low powered. Regarding spin, none of them achieve their potential due to sharp edges. We didn't want that. They are both, to me, pretty good at it due to different reasons. In Sniper, the added aluminum really helps at sort of disguising the pocketing and adding rotation to the ball while feeling crisp and, again, without that much pocketing. Just enough. The aluminum further assists with precision and playability duration, and the string should therefore be used at the lower end of your comfortable tension range. M8, on the other hand, accentuates the dwell-time and ball pocketing and this feels very obvious after break-in. The snap back is also high. To achieve similar levels of precision as with Sniper, the string is intrinsically less powerful, but the final product feels similar after accounting for the extra dwell time and pocketing. This is why M8 feels particularly low-powered fresh off the stringer, and before developing all the pocketing.
Both feel different when achieving similar performances. M8 tends to feel more comfortable due to the lack of aluminum. Most of the players can use M8 as as a serious power weapon precisely because they string it rather low and are able to achieve good launch while not feeling out of control. I do see the occasional report of people not getting enough power, and this is typically due to too high of a tension or simply because the string isn't appropriate in full bed for an entry level of play. Again, hopefully understanding the string, proper setup, and knowing what's needed at your level is important.
Thank you!
