I pulled my Bladez out a few days ago & have been playing with them since .. I was quite surprised how well the 3-4 irons hold compared to the R11's .. not too much difference IMO ..
Olympic 8th par 3 at 205yds and 22ft elevation .. wind was 10mph exactly 90 deg cross (no head or tail) .. wanted to land 3yds short with full back spin expecting a roll out to pin high .. on the replay I landed 2yds in front of the pin & the ball rolled out 1 yd only, leaving me 1yd below the pin .. that's good hold in my books for a long iron with no headwind ..
few shots with 3i in slight headwind also stops virtually dead; with some tail into flat green roll out 2yds and done .. i'm thinking I prefer my Bladez
