I've used Rhode Runner guide service in Marathon twice with good luck but they don't start guaranteeing tarpon till April 1st. I stayed at Bud n' Mary's in Islamorada a few years back in February and tarpon fishing was real slow so I asked the guide if we could find some big cudas since we got no tarpon. He must have thought I was nuts cause they consider them junk fish there, but they saved the day for me! Big 3-4' cudas on live bait in shallow water was a BLAST! Best advice is to target what's species is biting while you are there.I'll be in the keys in a couple weeks, any advice on what to use to catch tarpon? Artifical, live bait etc. Thanks.
