if i recall, all 3 of those are "latakia" blends. i'm guessing on the "billy budd", never heard of it. but i do know that Frog and Westminster are heavy on the latakia and have some oriental as well.

they will be very, very similar in taste due to the amount of latakia in there.
if one were a light english, or a light oriental blend, where there were more Virginias present, you could then taste a little bit of difference between the light ones and the 3 you currently have.

there are other genres of pipe tobacco as well, that don't taste anything remotely close to the 3 you have (amen to that).
right now, i'd say you're smoking full english blends, heavy in latakia, generous helping of orientals, and not as much VAs.
you may want to try different blends in different genres. the problem is, if you're still smoking cigars regularly, and those heavy latakia blends, then a light VA based blend might only taste like hot air to you.
