Slotboom's PLO book for PLO8?

[Lucere]

I posted this here instead of in the books forum because I wanted the O8 posters' opinions specifically. If this is grossly inappropriate, mods, please move.

Does Slotboom's PLO book, for those who have read it, directly apply at all to one's PLO8 game?

If not, is one able to easily make adjustments from his examples and strategy in order to indirectly apply them to PLO8?

Any thoughts on other PLO books in this application?

Thanks.
