thats why its an opinion not a fact
Well, my opinion of your opinion of his opinion is that it's an opinion based on no solid evidence.
In all seriousness, I think that the dampening does happen, whether it is noticeable or not, well, I don't think I bat enough to notice, but most bats change over time, and bats are different, so it's hard to quantify it. Common sense does say that if you sheath anything, it dampens the feel, I'm sure
@FattusCattus has pearls of wisdom to share on that subject!
Also, scuff sheets compress over use, so I'm a big believer of giving new bats their final 10-20 minutes of knocking AFTER the scuffing stage. Whether this makes a difference or not, I don't know, but just something I've always done since scuffing bats. (I think it stemmed from the Hammer Edge sheets, I always thought you had to give them some knocking after applying to seal them on properly and get the bat playing nicely)
