which style dripper?

Ive only used the black twist style and done 10-12 plants in a system, i am planning on doing 85ish in a SoG. Has anyone tried these? http://www.ebay.com/itm/100-Hydropo...ltDomain_0&hash=item23197f51be#ht_2024wt_1105

or these are even cheaper... Look just like the black ones i already have http://www.ebay.com/itm/NEW-Adjusta...ltDomain_0&hash=item565a5d6514#ht_6714wt_1054

I used to use these and they work well, except that I used a 1 gal per hr.. I have since gone even simpler. I now just start the babies in a 6 inch net pot with the water level about 1 inch higher than the bottom of the net pot, and drop it as the roots develop, with A daily spritz from a spray bottle until the roots hit the water. The only equipment in the containers is an air stone to put the 02 in the water. The simpler I get, the easier the grow goes. Peace & be kind
