Question about linkwheels

Hey BHW!

I have started practicing with linkwheels, but have a few doubts

1) I have read that open link wheels are better as they leave less of a footprint, is that right?
2) In the 2.0 properties, do I have to include only 1 backlink (with desired keyword) to my money site or can I include more than one backlink and keyword? Which is the maximum (if there is )? What about more than one article?
3) Which is the recommended amount of 2.0 props to use?
4) Is it convenient to use "2 linkwheels" to diversify keywords or just one?

Thanks in advance

1) Yes, it is better to leave it open. Less of a footprint. So in other words, create a link pyramid.

2) Yes, you can. I usually do 2 links per property

3) Very difficult to answer. The more, the merrier. No harm in having more properties. It'll only help your iste.

4) You can do as many as you want for various keywords.

i think the name should be changed from open link wheel (oxymoron?) to link pirate ship.

Thanks for the replies guys!

And when you include the link to the "following" 2.0, you use your keyword as anchor or just put the link? Or include it in an article with the keyword I am positioning?

Anyone?
