I didn't have either one before June of this year. Then I went bear hunting with a bunch of Tall Tines users. Keith Kocher let me try his TT out and I was sold.
I still have my Blacktail - it is very worthy of your consideration. That is what I shot my bear with. 53# with a Sitka Spruce arrow shot completely through the bear.
But, now I own two Tall Tines, one lighter than the Blacktail, one heavier. One standard grip, one lower grip. I love all three of them. Interesting side note: one of the TT was built from the left over wood from Gene Wensel's bow. Really cool looking bow.
