coyote- Sounds like it would work good where Im at then because almost all my taps are on steep side hills. The woods I thought about trying it on has probly 200' of elevation drop. It would be crazy easy to do if you ran 30 taps a lateral because you would basically just haze the whole woods in. The only thing Im kind of wondering is like I said will it keep on running? Is it a sure enough thing you could pay good tap rent and make money with it? What would be kind of a neat Idea is where these taps are the farmer has an old unused dairy pump in the barn all I would need is a releaser and I could be put vac on the end of the mainline or even use a sp22. Just run a one inch line the whole way, tap every thing in with 3/16 and see what happens? Theron
