Plain Deca, plain EQ or mixing half of each?

I'm beginning to plan my next cycle.
It will definately have 500mg Testex in it.
The second main ingredient will be either 300mg/week EQ, or 400mg/week Deca, or 200mg/week of each.
Would the third option be OK? I'm thinking of mixing them because my joints aren't that good, so Deca would greatly help, but I like EQ: side effects, vascularity etc. better. So do you think it would be OK to mix them like that?

Cheers.
