Personally, I would just test some and shoot whatever the gun liked best. I think it matters a lot more where you hit them and on the particular deer than it does on the difference of 20 grains of bullet weight.

I do think you will have better success on a marginal shot with a bullet that stays together. I love the Federal Fusion bullets in 150 grn from my 270.
