Bought a Noveske Chainsaw lower when they were on sale and just now getting around to putting it together. I haven't fully committed to an upper yet but was thinking I would go with a complete noveske upper. My question is I'm not super familiar with upgraded triggers but I am leaning that way. I have always used the trigger that came with the LPK (spikes enhanced, DD on my other 2 builds). Some one school me on Geissele, CMC, Timney, POF. HELP!!!!
