For the 301 I can say the biggest thing is control. It feels like everything will go in with this blade. It’s unique in the way it plays. It’s seems like a slow blade at first but it’s actually quite fast, it doesn’t propel the ball on slow shots but it does on fast ones. It’s only real downside is far off the table counters, which the power may feel like its capped. I don’t think it’s a problem if you find yourself playing close and mid distance. It’s great blade for developing touch and technique.
My friend has the 301T penhold version. It’s pretty much the same attributes just faster and it maintains a pretty low throw angle.
