my understanding , the blocks of 10 chances only better your odds against non residents only. residents don't have the option to select extra blocks when they apply for a moose tag, they only get to use previous preference points. my bear guide told me for a non resident, you would have to have around 350-400 points to be on the same level with a resident to get picked for a bull only. with over 50k each year in the lottery, the blocks of 10 are just a donation unless you buy tons of them.
