Hello wombat I dont have a champion juicer, but the large holed screen for my greenstar2000 is for fruit.I consider brown flax to be the best for omega3 fat%.Golden is higher in protein,depends on what your after dietarily speaking.I am vegan and flucuate between 70%-80% raw.Im consuming lots of local produce in central ILL.,apples are just coming in.Peaches and grapes and pears,easy and simple.I also grow barley and wheat grass the ultimate in enzyme replacement therapy.Growing grass is labor intensive but well worth the effort.Organic grass harvested and consumed within minutes is the freshest produce you can find!I own a vitamix5000 blender which I use regularly and works great.Dont have a dehydrator yet but I like the concept of dehydration.Live well and be healthy!!
