For what its worth. take what people say with a grain of salt, this is about YOU, just as with bike fit, these need to fit you, first and foremost. if you cannot get int the position you want, or are not able to hold it for your race distance, then they are not worth it.
that being said, in the past i have use:
visiontech alum base bar and their TT clip ons
(the ski tip ones
): great bars, get the size you need and never look back, fairly light and look good
same base bar with profile T2+ s-bend bars, look better to me, fit my hands/riding style a bit better, raced a full season on these.
2nd half of last season i switched bikes and tried out the full carbon easton attack bars. had some ups and downs with those, liked the no moving parts, only what was needed waas there, very light, looked aweseom, but the pads sucked, and i did not like the slight upturn so i finally ended up on the giant carbon aerobar.
the giant bar is a little harder to find, has a drop/swept forward base bar
(like the vsion one peice pro bar
), and push through extentions. i am using oval straight aerobar extensions.
the bars are fairly light, look good, and i love the no bends in the extensions
(not for everyone though
)
