DonM Steve are you using the Cobra Maxes? I thought you had not liked them.
I ask because I'm about to finally build my set of them.
Funny story. I bought a set of Cobra Max Superlite irons (and hybrids) because they were so cheap, new. I misunderstood the return policy and learned I could not demo and return. They went back in the bag and magically started performing as good as I can play. Needing a set for this Spring/Summer in VA, I grabbed another set of Max heads, 2 degrees up, from Hurricane (for me this time). I have a sweet set of PING AltaCB70 soft regular iron shafts going in them. I'm expecting similar performance as the heads are very similar, although the PING shafts are a bit heavier than the Cobra Superlite but still very light at 63g. Anyway, this is a half-baked attempt to reduce iron swapping in 2020.
