Tier 1 site backlink question!

Is it bad that I have about 15 tier 1 sites all linking to the same domain(different landing pages) via different keywords?

How long can I continue to link to my site without it looking suspicious?

For Example.

Let's assume I have a site about ORGANIC FRUITS

"best organic fruits" @organicfruits.com
"What are the best organic fruits" @organicfruits.com
"Healthy Organic Fruits" @organicfruits.com

"Best organic apples" @organicfruits.com/organic_apples
"What are the best organic apples" @organicfruits.com/best_organic_apples

It's only a matter of time until I run out of long tail keywords etc etc.

So basically how long do you guys utilize your 2.0 properties for?

Bueller, bueller, bueller, bueller...

Anybody have any advice?

Youre post is a little confusing, I think you might be over thinking this a little. You could build hundreds and hundreds of buffer sites back to your money site using identical anchor text and it would still not harm it. What you are doing (I think) sounds correct, you are building buffer sites and then targeting varied anchor text to various pages on your money site. Personally I would try and stick with one set of buffer sites (your 15 pages) one keyword, one target page on the money site, then build your second link layer, then move on to a new batch of buffer sites.

Thanks for the reply. It just seems to me like having 15 pages of the same anchor text and same EXACT url over the course of a few weeks would be a giant red flag. If this is what others do I guess i'll keep on trucking on then !
