Loc Line upgrade

Those of you that are using Loc Line, are you using a Shop vac or a dust collector for suction?

I have a really small 2 gallon shop-vac brand vac that I picked up from lowes super cheap. I will probably upgrade later, but it is working well for now.

When I finally do mine, I will add a standard dust port for shop vac. I have reducers that I can add to my 4" on the dust collection to connect to that if I want, although will probably need to also allow air in somewhere else there won’t be enough air moving through the locline to make it work.
