Believe I've decided on Ilium over the Heli bar-backs as I do not want 2 inches wider bars, which is what Heli's describes as their end result (though I do like looks of Heli somewhat better). Question for those having used Ilium's extraction tool, once the factory joined bar sections are separated, is it necessary to have their rental tool for any further separations? Didn't know if the factory pressing was so much greater than the reconnected assembly that future disassembly could be done without the puller. Thanks
