As I understand it, LW pro connects to a maximum of 5 ultrapeers. When a search goes out... those UPs relay it to X hops to other UPs. So if it's 3 hops... then I assume that I'm reaching 5x5x5 or 125 UPs. Is that the correct way to look at this?

Often what I'm searching for is rather obsure and I get no results. So is there any advantage to deleting one's list of UPs and getting another? Would that help? Or would I just be reconnecting with the same UPs by a different route?

If I do delete my list will they EVER come back? Or are does LW store that list as it does ban host?

Thanks!

Well, I've removed ultrapeers before & found slightly different search results. To be honest though, I've got no idea whether the results were different because of a change in ultrapeers or whether I was seeing different results because new hosts had logged on & so new files were available for sharing!!
LW won't ban ultrapeers if you remove them... you'll just connect to different ones

I've run LW and FW at the same time and have done identical/simultaneous searches and while there is on occasion some overlap, sometimes the results are soooooo different, I feel like it's two networks. Since I'm not sure it's a good idea to run both, I was hoping to expand searches by experimenting with the UP mix.
