Saw blade guide?

[Chunkytfg]

I'm fairly new to owning a decent Table saw and before I venture too far from 4x2 furniture into expensive hardwoods can someone answer what may be a fairly simple question.

I understand the differences between negative rake and positive rake angles on saw blades as they are meant for different machines but when it comes to Table saw blades why would I want to pick one angled blade over another? 10 degree, 15 degree and 20 degree seems to be the norm but I don't know why I'd pick say a 40T blade with a 15deg over a 40T with a different angle?

Can someone explain?

Thanks

Not sure if this allowed but this is a good guide.

I just contact a decent blade supplier and explain the situation, what I am cutting, type of saw and then taking their advice buy the blade. This works for both bandsaw blades from Tuff saws and circular blades from either Sheffield Industrial Saws - Saw Blades and Saw Blade Machinery or
