I've run through a reel of MSV Hex and mostly liked it. Hits as good, if not better, than RPM Blast. Definitely doesn't go dead as fast as RPM Blast. However, I keep finding myself wanting to put it a little above 52#. Unfortunately, MSV is pretty clear on the packaging to not exceed 52. Anybody have much experience with it over 52? Good alternatives that would play similar, last as long, up around 55 or so? A friend swears by Pro Supex Ultra Gear -- and routinely puts it up at 58-60. I played with it those tension in one of his racquets (which is very similar to my racquet) -- and it felt great up there. Plenty of pop, feel, etc. Thanks in advance.
