I have a good bit of experience with this as I have an enail or 2 going pretty much 24/7 when we are home and rotate a lot of glass. Any custom piece will throw a nub on for you but I have found that will actually knock your rig over more often than keep it out of the way. I found that some coils have a downward bend that will get it out of the way more easily without attaching it to your glass piece. The cord resting on the table instead of your glass makes it much less likely for your rig to be knocked over when someone hits the cord (and they always do). As far as pieces there are a lot of good stable bases but you would be doing yourself a disservice if you didn't at least try the FC-710 or other diffusion pump. Maybe they have ironed out the kinks with the heavier based version, that might be even better. But the FC-710 despite not having a big, heavy base is still pretty solid due to all of the water it holds.
If you are dabbing definitely try a FC-710 or other diffusion pump either way! I'm currently using my Jet Perc clone now just to rotate them out and I miss the awesome pull and flavor f the FC-710 already. Feels like a waste to use anything else.
You can see in the pic the little mothership clone has the straight coil arm but the FC-710 has the bend down that lets it rest on the table. Much better! I get these coils for CHEAP at Greenlight Vapes and have never had one burn out.
