How you set the volumes on the front isn't really a controlling factor for how you set the loop's Send/Return on the back. Yes, you want to avoid overloading the signal path, but how you set the ratio on the back is more about how much unaffected signal (if any) you want to keep in your final sound. In the Recto loops, which are parallel, you can never go above 90% wet/10% dry by inherent design. For almost all analog effects pedals, this will work just fine since few of the kind of effects that go in the loop require anything close to, nevermind above, 90% wet signal anyway.
Digital effects, however, can be a problem. Their internal circuitry converts the analog signal they receive into a digital one for processing, then back into an analog one at their output. This sometimes produces enough lag in the signal to cause phase problems with that portion of the original unaffected signal that also passes through the loop. This lag/phase problem can be enough to produce anything from white noise that washes out the rest of the guitar sound to a loud, overpowering whiney siren that's downright painful to hear. Not all digital effects produce the same degree of lag, so occasionally you may find one that will work sufficiently in the loop.
Out of the many combinations possible, there are really only two practical solutions to this problem. 1) Use all analog effects in the loop, completely avoiding the lag/phase problem. 2) Convert the parallel loop to a series loop, where no portion of completely unaffected signal passes through the loop, again completely avoiding the lag/phase problem. These are the only two solutions where you can be sure, 100% of the time, that you will not have any lag/phase noise no matter what combination of effects you choose.
