You don't say how you are planting. If tillage, you can easily stay at lower rates but broadcasting, then up the rates. Heck I've used 100# each of WR or WW and Oats before with tillage with no problem. For one thing, except in the south, the oats will die out after first couple freezes , and that is if the deer haven't already demolished that candy. The WR is going to die out the next summer and leave behind your clover so it is not really and issue and the deer love it in fall and its early spring green up. And talk about a weed free plot, heavy amounts certainly gives you that. Good luck.
