Bernardo B.wrote a review of SRAM PG-1070 Cassette (10-Speed) on November 16, 2015
Familiarity: I've used it once or twice and have initial impressions
Great range of gears for 52/36 chainrings up front. Can only be outdone by an 11-speed set up. Able to keep same cassette for all types of riding in San Diego/Southern California (flattish coastal rides, 4-hour rides up/down Mt. Palomar, the 100-mile Ride- Around-The-Bear in San Bernardino Mtns, 100-mile Tour de Palm Springs, etc.). Runs quiet and smooth with awesome Shimano reliability. Needed to add 2 links to my chain to clear the upper pulley from the 28 tooth cog and having the B-screw completely turned in as far as it will go (may need to go with longer B-screw). This is on a 6800 Dura Ace rear derailleur.
