I tried these because they were on sale at a great introductory price. What I like about these strings is they can generate massive spin they put on the ball that dive into the court. Higher kickers and nasty slices are at you command. You'll definitely want to string 10% under your SG/Multi tension to enjoy the same level of power you might have. Once the string settles you'll have fun. The downside is the fun doesn't last that long. String bed looses its liveliness, you know that sweet spot pop, somewhere around the 12-15 hour mark of solid baselining. While still playable and the tension seems to remain fairly stable, the level of precise control starts fading rapidly.
I'm a big fan of the spikey shark strings, great spin and feel at a very reasonable price.
