I do have the 5-pin flatliner and was happy with it this last season--it really lights up in low light cond. but,I am going to try the cosmic by impact archery next year.The trophy ridge sights are very bright but the cosmic is much brighter when you compare the two side by side.The flatliner is multiple pin and the cosmic is a single pin--depends on what your after i guess.I liked the T.R. but have heard others say the pins will break easily.I believe T.R. came out with tungsten(sp?)pins recently they should be very durable.hope this helps.
