I've got the One Length set up to the 4 iron in the graphite shafts and I'm starting to see some distance gaps shrinking between the 7i and the 4i.
For the others who've tested the F9 One Lengths, did you hit both the hybrid and the irons to figure out you gaps? I'm using the Rogue X 3h since Cobra does not make a LH 3h in One Length. I'm thinking I need to consider the One Length 4h and maybe the 5h to get a bit more distance on the long clubs to lead into the Rogue X 3h.
