Thanks for the pic! The Rean has a huge tush with the 4 x. Definitely would work.
Those WBT's look pretty sweet as well. Looks like they might even accept a bigger cable than the Rean just eye-balling it. Maybe even too big? You could stuff a small child in that gap, man.
They measure 9 mm on the WTB and I don't think a small child but a large cat for sure.
