Best Way To Do Reverb?

I have Sonar 8.5, but I don't think it matters as this should apply to any version. I seem to do reverb differently every time I start a project. Sometimes I use the native reverb on a sample library, plus Spaces; sometimes just Spaces. Sometimes I put a send on each synth in Console View, and adjust the amount of verb going to the Spaces bus; sometimes I put Spaces on each synth. Is there a best-practice way to do this, or is this another case of "There's a lot of ways to do this?" 

arlen2133 pretty much nailed it. I'd just add that we've been conditioned on what to expect when we hear sound in a acoustic space. I prefer the "bus to reverb" concept to create a cohesive space. I feel that too many reverbs create a sound that, consciously or not, we may hear as "phony."

Thanks Arlen and Craig. To be more specific in what I'm trying to do, I compose for orchestra. (nothing special, just a hobbyist). but I need to blend different libraries, currently GPO4, EWSO Gold, Dim Pro, Cinematic Strings, and soon to be, GPO5, which will be out sometime this month. I was using Vienna Special Edition, but gave up on it because it just doesn't blend well and causes other problems. Each of these has its own native reverb. I usually try to get all these native verbs equal as possible, then put them all in Spaces on a bus. EWSO is a wet library, GPO is dry, but has very nice convolution reverb, so I try to get it equal to EWSO. But sometimes I will not use the native verb, and instead use just Spaces, with sends. sometimes I will group all the woodwinds on one synth; all the brass on another, etc. Or I will just use one send for each synth, as all instruments on that synth pretty much have the same verb or lack of it. I know I seem to be making it more complicated than it really is, but when dealing with the orchestra, it really is more complicated. But there must be a way of reducing all this complexity to one basic approach that will work on all my projects. 

I think that can work and is pretty much on the basis of what Craig and I were describing.  The only added feature would  be the submix bus.  
Remember you can do all of this via an Aux Track and simply put that Aux/Reverb submix track in the folder with the library.  Keeps things nice and neat.

One other advantage of using a centralized resource for reverb is processing overhead. Reverbs will eat up resources so having one instance on a bus or aux track is preferable to several instances scattered around.

All great suggestions. OK, so last night I started doing this: Since East West Gold is my wettest library, I figure I need to set everything to that. Now, the East West "Play" synth has a reverb called EW Hall, which happens to be the same as Northeast Hall in Spaces (which is also by EW). So, I figure that EW has already figured out the right amount of reverb for each instrument, and indeed, if I turn on the EW Hall reverb for each inst. on the Play synth, it all sounds good (except for the timpani, they have Dark Abbey on that and it's way too much, so I set that to EW Hall also). Then, I put the other synths (Aria, Dim Pro etc) on Spaces, and set that to NE Hall (again, same as EW Hall, but here I'm using it with Spaces, whereas with the EW inst's. I'm using EW Hall right on the Play synth -  again, EW Hall on the Play synth equals NE Hall on Spaces reverb). This is giving me a good balance so far. I'm considering adding a bit of native verb on the other synths, to see if I can fine tune things a bit. And I need to decide whether to put Spaces on each synth, or send them to a bus. One advantage of doing it this way is that I now don't need to group inst's on different synths, so I can use fewer instances of each synth. That way the resource drain is less, and I can afford to put Spaces right on the synth. It seems to sound better that way. Anyway, I'll let you know how it's going, and thanks for all the help.

Sounds like you have a plan in motion Michael.  Let us know how it turns out (post examples!)

Actually, I like it better with the tails on. Maybe because i'm used to it?

I used to in my hardware days, have a reverb send and a delay send. I've gone off delay to a large extent, but where I do want it, it's usually on the one sound source, so I inserts works better here.
 

Hmm. I've read many threads recently on here and other forums where the tendency seems to be moving away from delays and back to reverb.
