the early armex cobra are powerful 80lb .but have a problem ,string ware from the brass coloured cocking rail on either side .the latest armex 80 self cocking bow has a solid deck so no nasty wear,the alloy frame models are better .if you get or have one please look inside the limb carrier as alloy sharp ridges are left and need to be filed off.providing the rubber buffers are placed either side the limb within the carrier the limbs are fantastic and will last you can shrink wrap tube them like barnetts limbs to help protect them or use insulation tape ..if you want to increase speed "power" remove 1mm of alloy from carrier top making sure its left flat and true.lube your deck with silicon oil to speed up again and reduce string wear.you can add preload again with a 1 to 2 mm spacer behind limb but wiill stiffen trigger effort ,try a soft grip rubber tube over trigger to ease the hard feel on your finger makes it a little bigger area to pull too..enjoy
