Using 2 wireless systems

Currently using. G30 between my guitar and Helix and thinking about getting a second wireless system to use between my Helix an the PA.  will latency become an issue of any quality concerns?

    Can’t see a problem technically apart from the extra compression added by the second transmitter, and the more transmitters you have on stage the more the chance of a frequency clash and drop outs.It’s unlikely you’ll experience any real latency problems. I am questioning why though your just adding to more possible places for faults to occur .

    Couple of reasons.  Quicker setup and one less lead to trail over the stage.  Probably more trouble than it's worth though

    Would the G70 be a better option? Has 2 outputs instead of 1, although not sure of the physical location you're putting it in and your stage layout etc.

    Just an option though.

    Not really, I would need one receiver next to me and the other one in the rack with the desk in some way away.

    There was some debate on here the other day about at what point you can hear ( feel?) latency. Not sure what the answer is but around the 12 ms mark is apparently noticeable for some folk, definitely noticeable over 20ms ( according to something I read in SOS). So if you add the latency of two G30s together what do you get? 
    Quite a lot of cost and faff in doing this, as the cable from your board to the amp doesn't move and can be taped down it's not overcoming much of a problem ( or I assume it's not anyway).

    The latency adds up which then quickly becomes apparent the further you move away from the amp. I have the Sure GLX which is very good but I notice the latency when stood about 5 metres from amp....more so than just using a long cable. Adding other digital processing into the chain e.g. I also have an FX8 also becomes more noticeable. Moving back closer to amp and the latency issue goes away. In summary I find that wireless systems are fine but they compound the natural "sound wave" latency...as you would expect.

    Hadn't thought  about the Helix; Line 6 say it's sub 2ms latency plus about 1ms per loop ( not sure I understand why but it's their comment). The more you add up the closer you get to something noticeable. Found the figure on the G30 now: 4ms.

    So G30 + Helix +  two loops + G30 = 12ms

    The helix loops add latency due to D to A and A to D conversions required (pedals are analogue, helix signal path is digita).
