I don't feel anything that I could say would necessarily be of use to others; I am not very high level, and don't find that much of what is said about blades is stuff to which I can relate.
I am currently using the H301 as my main blade, and bought a second as a backup, so I really like the the play I achieve with this blade. I suspect it has a "low throw", is nowhere near as fast as the Off++ rating would suggest, and the ball generally goes where I want it to. I moved to this blade via the Fang Bo 2 from my Hurricane Long 3 after breaking my wrist (not TT related; it would take some heavy whip action to actually break the wrist!), expecting it to be a little faster, requiring less effort. I find the 301 more comfortable to use than the FB2, but would be pushed to say it is actually faster or slower. I think I can get more speed on it, and probably stronger spin, when I get a shot just right. I am impressed enough to be considering finding an N301.
To give context, I am in my first season of league play, in the bottom division of the city league. I am captain of the team, newly formed by me, in which I play number 4 of four, and we are in the top 2 of the table at the moment. I have an 80% win rate in doubles, but only 30% in singles. Should be better, but there are things I still cannot do with my wrist, which now has a metal plate holding bones together. I tried to get them to install some bionics, but no such luck.
I got my second H301 for £30 including shipping. Absolute bargain.
