Integy has this thing where they discharge at 20amps so the numbers look super awesome, but not industry standard these days...most companies are matching around 35+ and giving more "mainstream" numbers.
I've had integy cells in the past and liked them, but for now, If a cell can handle a 35+ amp discharge during cycling/matching process, you know it's gonna work for you in your car. 20 amps can't really effectively weed out the weaker cells.
Personally, Id stick with Slingshot, Promatch, SMC etc
