Blades are less about wind resistance and more about aiming stability. They don't suit everyone. The best way to try it is to set up your bow as normal. Draw up and settle into your regular aiming pattern. Move the bow off target (left or right) and back again. See how long it takes to settle. Switch your longrod to a blade longrod and do the same thing. See if it makes a difference. For me, it settled in about 1/3 of the time. very noticeably quicker.
The idea is that the elliptical shape, because it's stiffer on one plane, reduces movement far quicker in that plane. It can exacerbate any up-down issues you might have, as it is inherently weaker in the up-down plane. I'm unconvinced that the SF variants have the same properties as the Fuse in this regard, due to their construction.
I'd also perhaps argue that a stiff tubular longrod is probably better, but hey, I use a blade as I found it works very well for me.
