Hmmm This is beyond hard to choose. I'm going Swiss style on this one! However....
At the keys a year or 2 ago, I fished 2 days guided. First day all we fished for was tarpon. I was so freaking frustrated I could kill someone. The fish would not eat.
Second day did half bones and half tarpon. Caught first bone. Still have not caught a key tarpon.
Tarpon are much more frustrating b/c they feed mainly at night time. Yes you can catch them during the day, but they feed most heavily at night time, gorging themselves. For that very reason while at the keys I prefer bones.
But you really can't compare totally different fish.
You could say do you prefer Keys bones, or Bahama Bones.
Keys tarpon or Costa Rica tarpon.
I love them ALL!
