@Przemooo You are getting into the discussion area of weight distribution vs weight.
Anyone reading my writings on this over the last decade plus KNOWS I value mostly what many consider a "heavy" overall weight - I like blades to be in the 85-115 gram range... but would also know I value weight distribution and the handle ergonomics (thicker, longer handle and shaped a certain way).
I am pretty famous for my series of posts on the "Der_Echte Beast Mod" which is a name I gave to my modification of modern blades to fill in the empty space in the handle pieces and/or throat of the blade with hide glue and various fillers (pieces of metal or wood) to make the weight of the blade go lower, make the blade more solid and easier to whip in my hand.
There are many factors in the dynamics of what makes a bat accelerate and accelerate EASY. I want EASY Acceleration. I want it to be almost effortless. I want the dynamic of the blade to help promote blade speed production and control of that.
Having said all that... if you have a blade you LIKE and want to go in this direction a good deal, but not want to perform open heart surgery on your blade... then get sum grip tape you like and grip tape that sucker with a shape you can like and control easy;
You will get 100% the effect of a Beast mod, but you will get almost halfway there instantly.
For MANY players, a good grip tape job is plenty enough improvement to satisfy them (enough).
Consider grip tape or a Beast Mod on the blade you like.
