I have a brand new condition 08 xforce ss. Not a mark on it, 27.5 mods and 29 mods set at 60-70 lbs set at 71 now. Setup with a new QAD HD 129.99 a new Viper slider sight .019 pin 99.99, a pse stab 34.99 a custom sts 20. string leaches, peep. It shots a 375 gr goldtip xt hunter at 298 at 27.5 draw. Very quiet and no vibration I have had this about a month and shot it maybe 50 times. I bought it new as a 08 left over. I will let it go for 400 bare or 550 setup and both of them prices are tyd and a steal.
