I'm not sure if this helps or not, but I ran a heap of tests (at level 20 as I'm Vet status) on the test dummy at Theramore, and tried heaps of different enchant combos, including many weapon chants. I'd say that at 20 it wouldn't be that far off how 29's would perform, although I know 2ndry stats have less of an effect at 29 than 20.
I found both Vers and Haste to be the better performers, and more consistant DPS. In the end, I chose to go with Haste as it seemed to DPS spike more frequently than Vers when running double Crusader. Vers was more consitant DPS, but Haste has some pretty cool DPS bursts every so often, and when they occur in bg's or arena................ it's lights out.
Not sure how Haste would go on single handed weapons though, Crit or Vers may perform better given you already have a faster weapon speed. You probably have less to gain from Haste with single handed weapons.
To compensate for not using Crit or Vers chants, I tried to increase Crit via gear, by missing out on some Str and possibly Stam for the sake of extra Crit. I do feel you need a healthy amount of Crit also.
Anyhow, hope this is of some assistance.
