Is there one book that sets all tennis lines?

[beefcake]

Kinda like the LVSC for tennis?

Would it be bwin by any chance...?

Just wondering if one book sets the mark and all others adjust according to these inital lines...

When I need a line that isnt out in american book i look at www.oddsportal.com, usually StanJames is first to post them... I dunno how the lines are set though... was just thinking about this actually.
