Question about using Youtube & Clickbank

So after trudging through many a product (a lot which made me want to run away from their page.. ), I finally found a product that I know something about and I feel comfortable selling on clickbank. Now I thought about various strategies, and one of them is using youtube. As you know, youtube allows you to put a link to whatever it is that you're selling in the description. The clickbank people selling the product have a webpage where they sell the product.

My gut feeling is telling me, first create a landing page and then on the landing page use the my clickbank affiliate link to direct people to the selling page that the vendor has created. However, I'm seeing on youtube various people using their clickbank affiliate link to go directly to the selling page.

The reason I ask is because I know that youtube is definitely against having direct links to Amazon, people putting their Amazon affiliate link right on the video. So, I wonder if its the same for a clickbank affiliate link, even though, in this instance, the product varies and you're not going to clickbank, you're going to a webpage created by the people selling the product, with a completely different url than clickbank.

So, the question is, is it smarter to use the landing page and then direct the persons interested to the sales page, or go directly from youtube to the sales page? Does youtube frown upon using an affiliate link under this scenario? Any info appreciated, thanks.
