I did not like this string when I playtested it.
One of the more dubious results in USRSA playtests, unfortunately, is the tension retention category because there is no instrument--ERT, Stringmeter, etc.--requirement. And when the USRSA subjected Premier LT to their own, the result was quite the opposite of the high rating it received.
Here is the result from the playtest itself; recall the test string, which is Prince's Original Synthetic Gut, loses but 9%:
"After 24 hours (no playing), stringbed stiffness measured 64 RDC units, representing a 14 percent tension loss."
Under USRSA lab testing the drop was even higher (see the result here):

Personally, I found the Premier LT had little feel too.
In this regard it is comparable to me to Wilson's Hollow Core, another bust IMO.
If you just happen to like its overall performance for some unknown reason, consider Klip's Excellerator as a better equivalent at the same price point.
For someone just caught up in comparing polyester with nylon somehow, try out Tecnifibre's MultiFeel first. Better yet, go with Babolat's Addiction and/or N.vy synthetic gut.
To me Premier LT's lone recommendation, when compared to other choices, is that it is out in an 18 gauge.
Prince's worse fear ought to be that it will give their Premier with Softflex--to me the better string by far, though designed far differently--a bad name by mistake.
