I'm all for minmaxing but generally speaking you have a primary attack (grap, punch, kick) and only do the other for tierups. Which you might just be ambushing as a ranger so that would rarely even be a thing. So it really doesn't matter much.
I use disint flaring gloves and boots for like 70 levels (still use the boots on living at cap) and seemed fine. I'm sure grapple would also have been fine. If you already have a set one way or the other I wouldn't say it matters enough to try to change, as I'm assuming you're juggling between the Duskruin sets they're all basically the same stats.
