77mm VND Filter that works with RF 70-200 2.8 Lens Hood

[JCin]

Hello, I'm looking for a Variable ND filter that stays at 77mm thread for the RF 70-200 2.8. The lens hood has the door on top that allows access for adjusting circular polarizers and Variable ND filters. Most VND filters go from a 77mm thread to 82 on the outside. In order to use these with the lens hood it is really difficult because you can not attach it to the lens and put the lens hood on. So some how you have to do this with the lens hood attached. The Polarpro VND Peter McKinnon Edition II looks like it might be what I want.

 Does anyone have experience with these or know of other VND filters that I can use with the RF 70-200 2.8 lens hood? And what I mean by use with the lens hood is, being able to put the VND filter on the lens and then attaching the lens hood. thanks
