Based on your description, I think the Tropos paddling suit will work just fine. While the Tropos isn't as breathable and you'll get what you pay for in durability - if you're only using it a handful of times a year it could be well worth it. I used a semi-drytop with a non adjustable neoprene neck gasket for years and thoroughly enjoyed it. As I started doing more early and late season kayaking in colder waters (Colorado) I finally upgraded to a top with a latex neck gasket to stay as dry as possible. I also have some Kokatat bibs made of Tropos that I use a handful of times a year and even though they're not as durable and breathable as the Gore-Tex version, they work fine for the few times I need more than a drytop. On a side note, I did notice that Kokatat is calling their neoprene neck gaskets "adjustable" yet I don't recall seeing that - I recall them being only "cone" gasket that's not adjustable. For what it's worth I think the cone gaskets (if the right size for you) are dryer than an adjustable (hook & loop) neoprene gasket. Just make sure the neck gasket fits you well - too loose and you'll get too wet.
