The last 3 blades I ordered had a better fit into the shaft. There is still a bit of a gap, but not as bad as some of the blades I recieved in the past. I had to take a sander to one once. That said, I have never had any performance issues or breaks at the connection point.
i just picked up a base blade (BC14) to go in my true 6.0 shaft and noticed the gap. i take it that this is normal? how big of a gap should it be?
i kept trying to smash it in and hopefully didn't hurt the shaft. it started to bow out a little so i stopped.
that being said, i took some shots yesterday and it felt good.
