Due to various right leg problems, knee and hip, I don't think my Heritage sit in kayak will work for me fishing. I've read that sit on tops are easier to get in and out of. Now, I found a Wilderness Systems Tarpon 120 on Craigslist. I would doing primarily fresh water, small to medium lakes, a few rivers. Does a unit like this make sense. I'm going to try drylanding in and out of the sit in before I drive 2 hours to see the other one. Now that I'm retired I need to make up all that lost fishing time! Thanks for any thoughts.
