I have the ergo version on all my bikes; great bars wrongly named. The 'ergo' has nothing to do with the curve, it has a flat top to rest hands on .. maybe 'aero' would be apt. Neo classics will check all the boxes that SL-70 does with tumblr fame and longer drops.
I like the Zipp Service Course SL-70 too... need to check the reach / drop etc after doing a fit.
