The "Teddy Hopper" recipe that Maltose Express has was the result of the first cloning attempt for the beer. From I was told, it finished with a maltier base and provided a better over all balanced beer.
The "Heady Topper" has some where between 6 to 8 hop additions in the boil, in addition to a dry hop.
I recently brewed this beer, and compared it against a can of The Alchemist's Heady, and the flavor and hop profile were definitely dead on. The only difference would probably be from the Wyeast 1056 instead of using the Conan yeast which you can't find anyway (unless you try to propagate it yourself)
It seems that Alchemist MAY have changed the recipe or process recently. Many of the cans I've had in the past have had a significant amount of hop matter in the can (hence the "DRINK FROM CAN" label). The last couple of four packs I shared with friends has had NO hop particulate in the beer, the beer seems clearer (filtering now?) and the flavor profile seems to have changed a bit making it a better balanced beer and not the total hop assault on all your senses.
