I now believe this particular grip is only suited for small diameter light weight blanks!
Almost had it reamed out to put on a DS822 Med/Lt blank, but the grip suddenly crack apart "not enough cork / strength left when reamed out and this is noticeable even after putting through the smallest size reamer. I think the manufacturer / Mudhole need to way more add suggestive compatibility or non-compatibility comments on not only this product, but many others I find very vague. Hopefully no-one else wastes $16 (a lot more for me in CAN) on trying this and have to once again start the build over.
