One of the few boats out of WPB that I haven't been on but have heard its a good boat and crew. Hope you have a great dive.
My recommendation is that you dive every day for a week and then if you still want to switch to one a week, fine. But my understanding is that you want improvement, so that's why I'm recommending the back to back dives.
I dove the 13th on the captain Dan in pampano. No current and vis was great. Dove with sfdh. Did two great dives.
