i've only hit breifly with a long 5. i own a long 3. it's basically identical there are maybe a couple of differences. Firstly the handle is not conical flare is more oval flare. secondly the sanding isn't quite as high quality thirdly theyre 5 grams lighter. but for me not worth the extra but if you want to feel like you got the number 1 blade and have the money get the HL5, if you lust for it you'll get one at a later point anyhow.
I might consider the b-2 because of its performance to price ratio, plus i love the color red better. haha.
So, the handle of the B-2 is thicker? i have a big hand, so i find my pg13's handle small for me.
Secondly, sanding not of quality, but i can just sand and prepp it before gluing rubbers on it. right? or would it damage the blade and handle's paint and all?
And lastly, b-2 is 5gms. lighter, but you can still buy it heavier (in 90gms), right? how may gms is your b-2 blade?
