There’s not a lot of love for thin handles,,, interesting
No I would agree however you can modify a thin handle with tape etc and at least you can always go bigger if you choose to - this is something you cannot do with a thicker one (unless you get a rehandle of course) This is what I tend to do wit TK bats - I also enjoy it too it allows you to get the handle feeling exactly how you want it.
If it's too thin, you can pad it out to get the right shape but it'll never be as good as if it was right in the first place.
