For those who have thrown "The Jackal" what is your opinion of it?

Those numbers are unreal, RG 2.46, Diff .060

For me it is very strong - a little too strong for my THS league shot right now.  I got it mainly to have something to go to when I run into heavier oil at tournaments or if my THS is more oily.  But I am a little on the slow ball speed side (14-15MPH off the hand) and about matched in revs (~250).  For someone more speed dominant, and/or more oil, it should be great.

While it is super strong, the cover does keep it from going into an early roll and rolling out - like a dull Hyper Cell for instance - so it will be more versatile.

I changed the surface on my Jackal in an effort to use more than just the first 1-1/2 games as the oob dictated on my league condition.
I tried polishing oob and found for me it got greater length but was too twitty at the break point.
Then, I hit on the combo for me. I sanded the ball with a used 500 abralon pad and polished it. Ball will play in the oil or punch out to the dry and give me a more predictable break point. Heavy roll & carry was great. I can now use all three games if I wish making easy moves as the shot migrates inside.

Ball drilled pin in ring finger mass bias 2" right of thumb.

My specs  5 -3/8", 3/8 up = axis point , 14- 15 mph, tweener

"like my Jackal - love my Covert"

I have kept my Jackal at box finish.  Due to having a lower rev rate, I am able to use my Jackal on most THS patterns.  The Jackal does not lose hitting power.
