What is the poundage on the triggers that you have been used to using? What other people are using means nothing.
If you are used to pulling standard factory triggers, then don't even consider a 1 1/2 lb trigger.
Another thing to consider, do you ever loan your gun to anyone else? If you do, and you hand them a gun with a hair trigger, they may accidentally shoot you or your truck.
3-3 1/2 lbs is fairly safe for most people to start off on but not for novices.
Good luck1
