I googled Pro's Pro Strategem as well and found the review below. I am looking at picking up a reel myself.
Power: Really good controllable power. Gives you little extra power without fear of hitting long. 8/10
Spin: Excellent access to spin. Felt my topspin shots had little extra kick and slice stayed nice and low. 9/10
Control: This string has nice feedback and I found it really precise. Could hit my marks with confidence. 8.5/10
Comfort: No problems with this one. Really comfortable both with either a full bed of this or in hybrid setups. 8.5/10
Durability: String played same way in the beginning and in the 10 hour mark until a restring was needed. 9/10
