I use mostly stop-loss traps for rats also,and have B&L Shur-holds, round pan Victors, and I tried a few new Dukes this season which I got from Tom. I have always liked the B&L Shur-hold design over the Victor. When setting the Victor's, you have to flip the pan out of the way to set them, and the pan ends up a little high when set, as the guard goes under the pan. This makes for toe catches with this trap.I have caught many mink toe nails due to this high pan situation. The new Duke is a nice trap, as the spring is very strong, and designed like the B&L. The guard spring is strongerthan the B&L Shur-hold. Very worthy successor to the old B&L. I have even used the old #1 B&L's in dry sets for mink and have held some large coon too. Just watch how you cover them.
