Different books for different sports?

[Jibba]

I know about the "Must have books" thread and just had a question which wasn't specifically addressed there. I was wondering if people find that certain books are better suited to certain sports? Basically, I've started playing small units on NHL and NBA games but wanted to branch out a bit from Pinney. I noticed that the "Must have books" thread recommends Skybook for the NBA because of the free 1/2 point (although I have been playing more MLs than point spreads in both NBA and NHL games). I also noticed that Carib has -105 for one hour a day (although not sure which hour) and that Cascade claims to have it all the time (if requested upon signup).

So does anyone recommend a particular book for NHL and/or NBA lines? I'll likely stick with Pinney for football, but would love some advice on where to branch out to next based on what I'm looking for. Thanks in advance.
