Bloc_Locs are the best! I personally don't think you need a set of HST rulers since you can cut small-large HST with the larger ruler. You will likely want a set of flying geese rulers unless you only ever make one size geese. I have a 6½" HST Bloc_Loc and a number of flying geese Bloc_Loc rulers, I use them all the time! I will cast my vote for the flying geese ruler set just because I think everyone should own these :-)
