well after researching this subject a bit more, i've decided to go with the meyle hd bushings. the x has 43K miles and the bushings are the originals. i only drive about 7-8K miles a year so i should theoretically get at least 5 or more years out of the meyle bushings before replacement is required. my reasoning was that it seemed the powerflex application is for those that wanted to "tighten" up the front end a little and increase turn in and feel. my opinion is the the x feels plenty tight and has great turn in already. in addition, it doesn't appear that the powerflex bushings have an more reliability or longevity over stock. this install will happen within a week and i'll keep you posted as to my findings.
