I use twine at the very bottom of the handle to minimize flex which could lead to shoulder cracks (so far ive not had any so i think its doing the job . Before this i had no twine at all and did get a couple bats develop shoulder cracks ) .
I use elastoplast because i can get a tight bind without lumps and it is thinner and lighter . I try to get the lightest, thinnest handle possible . I also cut one inch off the top of my handle to get a 'super short' handle .
Ive been weighing things whenever doing these mods .
A full handle of twine is usually between 11-14 grams . My combo of twine bottom and elastoplast is usually between 5-8 grams . The top inch of the handle is usually between 11-15 grams . So i can often lose close to an oz in my handle weight by doing these mods . Its nice when 2lb9 all of a sudden is 2lb8 etc .
Also , i reckon changing twine for elastoplast feels like going down thickness by about .5 a grip . If I feel i need more off or the semi ovalness of the handle is not quite right i have the chance to sand /shape the handle a bit while theres no twine/elastoplast etc on the handle .
I find the elastoplast option particularly helpful with my heavier bats . Ive noticed that the G.N Kaboom basically takes this exact approach - shorter , thinner handle with twine only on the bottom... although it has white medical tape instead of elastoplast.
I do more or less the same thing for the same reasons but I only remove the binding from where I grip the bat
