I'd probably go for the Geoffs .36's, potentially try a few different weights and see what works best?
The drm is 2nd hand and had been advised the guy ran it kn 36's but occasionally 32's as they got tontarget a bit quicker. All new to me I'm usually running a normal aeg on .28's
The flight time between weights at DMR range will be negligible. I'd go for the heavier weight really.
.32g might be marginally quicker to target right on your MED, but .36g will win out anywhere else. Of course, I say that, but I run 0.32g Vorsk because I'm a cheapskate.
