I am impartial. If I get used to a head heavy blade, it is fine with me. I am also fine with the extra feeling in the handle. A center balanced blade or a handle heavy blade is a bit easier for me to get used to. But, I can get used to any of the above options.
My experience is, different blades, different balances, allow you to do slightly different things. I could develop technique around any weight balance within a fairly reasonable range. It makes no substantial difference to me.
But for sure, a blade with more weight in the handle that is the same weight as a blade with a hollowed handle will feel like it is a lighter blade: part of why is: if you hollowed out the handle heavy blade and removed the same amount of mass as was removed from the blade whose handle has already been hollowed out, the previously handle heavy blade WOULD BE a lighter blade.
Conversely, a blade that is 85 grams with a hollow handle, if you put back the material that was removed in the hollowing, will actually be a heavier blade.
So, usually, a blade that was 90 grams with 5 grams removed from the handle which now weighs 85 grams, will still feel kind of like a 90 gram blade.
But, again, if you are used to a particular blade or setup, and have developed your technique around that, something with a similar weight balance is more likely to work for you.
