Bummer! offsets arn't the best for coons. You should look at the Lil Griz Getter'z They are dogproof and work very well. Lenons lures are very good and work well.for coyotes. 1 3/4, 2, or 3 will all work great. Duke is a good brand to go for if your watching your budget.
The two webs gen recomended are great.
Have fun trapping,
Sam
