A-Class Visual Design

I have the following guitar effects pedals: Boss TU2 (tuner), CS3 (compressor), SD1 (overdrive), dunlop wah, dunlop volume ped, Boss RV2 (reverb), DD3 (delay), CH1 (chorus), and finally NS3 (noise suppressor).

This concerns the NS3. It's got send-return jacks on it, besides the input-output jacks, and I'm trying to decide if they're worth using.

Here's my current chain:

Guitar - TU2 - vol - wah - CS3 - SD1 - Input to NS3 - Output frm NS3 to Input of amp; Effects send from amp - CH1 - DD3 - RV2 - Effects Return to amp.

But, would a better chain be one like:

Gtr - Input to NS3 - Send from NS3 to vol - wah - CS3 - SD1 - Return to NS3 - Output from NS3 to Input of amp; then Effects Send from amp - TU2 - CH1 - DD3 - RV2 - Effects Return to amp.

I'm hopeful some knowledgeable fellow guitarists can follow that and give some advice on setups that work. I know it's an individual thing, just want some ideas on what you guys do or would do.

Thanks in advance,

Chris
