[Closed] whats the difference in these chainsets? and which one???

[url= http://www.chainreactioncycles.com/Models.aspx?ModelID=22924 ]Deore M532[/url]
[url= http://www.chainreactioncycles.com/Models.aspx?ModelID=40496 ]Deore M590[/url]

guessing the M590 is newer?
same price though, you'd get the M590 right?

alternatively how do FSA chainsets match up? looking at the [url= http://www.chainreactioncycles.com/Models.aspx?ModelID=35722 ]Moto XC[/url] and [url= http://www.chainreactioncycles.com/Models.aspx?ModelID=12730 ]Gap Quad[/url] on CRC

oh, and can i presume that i can adjust the chainline with these? currently my ISIS cranks are too far inboard for the ft mech to work well. i've only used HT2 once a few years ago and found it infuriatingly unreliable. but this ISIS set up is REALLY pissing me off, and i can't afford another sq taper middleburn set up. £50 doesn't seem too unreasonable once i've factored in the cost of another ISIS BB...
