These days, I play almost exclusively in church, so yes a very clean stage is preferable and I'm not worried about drunks spilling their drinks on my pedalboard. However, the issue is more of organization. In my case, i have an eventide H9 in the loop that I'd like to use and a few overdrive pedals that I prefer to place in individual loops.
Option 1) Leave everything but the remote behind me or even to the side of the stage, with Kemper's limited midi controls (I have a midi controlled multiple loop device for my OD's) I'm stuck only making changes to these devices on Rig changes. This means that I have to create a lot more duplicate rigs for nothing else than to send a midi message. BTW, to make this convenient, requires a lot of rack equipment.
Option 2) Leave everything except the Kemper at my feet. Then run four guitar cables, a midi cable, (because I still want some messages sent on rig changes) a cat 5, and likely a power cord as well. All so I can needlessly sit my unpowered head somewhere else, and I use IEMs so there no point
Option 3) Put my Kemper on my pedalboard and leave everything wired up
All three option are less than ideal. I really need a floor model, so much so that I even considered the Helix, but won't because of the above mentioned flaws.
