Dips on V-bar or Straight?

I currently do the V-bar more but I’m not sure if I should also start using the straight bars.

the straight bars will hit the triceps more, the v-shaped bar will incorporate more of the chest.

Whats a good way to make my own v-bar without having to set up for 13 minutes and steal 2 olympic bars?
