Which thinset for CBU to OSB?

Hi all,
Wondering your thoughts on which thinset to put under cbu to 3/4 osb subflooring.
Normally I use a modified. But have heard some recommend un-modified?

And lastly, if I was to do a second layer of plywood for height (if needed) before cbu, would you guys recommend troweling titebond2 for the ply to osb bond? Maybe scuff the osb to help with glue?
