I've only sailed the newer style or older boats that have already been upgraded. But my common sense tells me if it is working fine and isn't giving you issues, I'd stick with it. Again, no experience of the older style (except as a kid 45+ years ago), so I have a uniformed opinion. I imagine there are many, many still out there, sailing just fine with the older style. I think it's when you get into consistently much heavier winds and waves, that I've read it becomes more an issue, with popping up. Great forces = likelihood of malfunction. I've never read of the new style having those issues.
