in my experience. lux alu has more control at a lower tension for 4 or so hours. around 54, 55 for me. at tensions around 57, 58 it has less control and spin. this is all fresh strung mind you. after 5 hours the higher tension has more control. there is definitley a more pronounced ball pocketing effect lower and i can generate more pace and precision with a apdc freshly strung with alu around 55lbs.
what i usually do is string at 57 or 58 and have it play bad (for me) for a couple matches then it settles into a lower tension until it goes dead then i restring. kinda a compromise. otherwise a fresh strung alu at 55 is too powerfull after 5 hours or so.
If you ask a lot of experienced stringers - also guys like JayCee, TennezSport and other string guru's - they will all tell you, that you get stiff poly strings like Alu Power to lose its elasticity and good playing characteristics sooner, when you string it at too high a tension.
Pro players don't care, as they only use the same string job for max 1 hour in match play and then maybe for 30 minutes practice the next day.
But for ordinary folks, you prolong the life of Alu Power by going lower in tension. I string my Luxilon Alu Power in my crosses at only 50 lbs (98 SQ" frame) and 48 lbs (95 and 93 SQ" frame), and I feel like I get more life out of it, compared to when I strung it at 58 or 56 lbs. I still have nice control with it.
Stringing poly strings at too high tension ruins the fibres inside the string, which is why you see the recommenation for 10% lower tension on almost all poly strings these days.
When my strings lose too much tension after 4-6 hours, I install a bunch of string savers to stiffen the stringbed and raise the tension around the sweetspot a bit (I lose bit of feel from the string savers, but it's not so much as some says), and I get 2-4 hours extra life out of it....unless I broke the hybrid strings prior to that of course
