I was thinking of getting some elka shocks for my dvx I did'nt know if there is much of a difference between shocks with or withount resivors I want to race mx

 

Yes!

 

So do you think I should go with rezzies or without.

 

If you have the dough absolutely go with the rezzies. They add the ability to adjust the compression, and keep the shock fluid seperate from the shock body. This helps greatly reduce heat fade. If your gonna spend the money to get elkas you'll be kicking yourself if you don't get rezzies.
