1.7 is a good speed to start . but do not be afraid to speed up the water is warming up and the speed does go up . when I troll I try from 1.7 all the way to 2.5 . also I will troll at one speed for a while and just slow down for a 100 yards or so then speed back up just too change the lure action. GOOD LUCK.

TIME TO PUT SOME FISH IN THE BOAT.
