Yes you can expect good results with your outfit as long as your broadheads are very sharp , you have good arrow flight , and confine your shots to the conditions you stated . As far as vanes off the shelf you should not shoot vanes off of the shelf as your arrow flight will suffer greatly . We all have bad days but a good habit to get into insted of putting your bow away when things go bad is to settle down go back to the basics of form follow thur and release and end your practice session on a good shot always !!! ( A great confidence builder )
Good shooting and have fun
