Was looking at the eve flow for a little while, but tested into a Hzrdus Yellow 75 6.5 with ~110 avg SS... loved it but the miss would always be a push right (as I normally play a draw). I recently switched to the Hzrdus Black 75 6.5 and absolutely love it. Almost canceled out the right push. The Hzrdus line and definitely the black get heat from people for feeling like telephone poles, but I love the stability. The black helped me with dispersion and with a slightly lower launch angle (I also turned my g400LST down from 8.5 to 7.5 <I think> so that helped with launch) but I’ve picked up distance with better dispersion.
id recommend trying shafts on a monitor to see the numbers, but since the new driver will probably be really easy to swap out shafts, you can always pick up a used one and then sell it if it doesn’t work?
happy swinging
