BV Build Suggestions

Hey folks, I'm a forum stalker, and review lots of builds about Blade Vortex. I want to make a BV guy soon, but unsure which type of build would provide the greatest enjoyment/strength.

Ele conversion BV? Obliterate Wands? Standard Crit? Currency isn't immense, I think I spend about 3 ex or less, preferably alot less.

Anyways, if someone with any experience between the different types wants to chime in, definitely looking for some input.
