Hello again. I ordered an impact wrench, and am trying to find a a site to buy both dr. pulley 5 gram sliders and clutch springs. I am thinking 1500 as I have read that 2000 is probably to stiff. Any recomendations on the smaller springs? I saw that you can buy a set which comes with three different stiffnesses... Any advice at all when it comes to these clutch springs is greatly appreciated...
