How healthy is your bank account?
The best 3- piece IMO is the new(ish) Quickblade V-Drive 3-piece. Given your weight, you might like the 101 sq inch one. You don't need to go any bigger in that model. The cool thing about it is that it screws together using a hex key so that once it is assembled it is just like a normal paddle. Usually, multi-piece paddles have annoying clips, notches etc to hold it together, but the QB doesn't and is a work of art. Comes in a nice bag too. You cut it to your size just like a normal paddle - it's not an adjustable.
I think it's pretty much top of the tree right now in terms of multi-piece paddles. But it's for people who are serious about their paddling and it is expensive. So only you can judge if you belong to their target demographic for this paddle. I got mine as a Christmas present so I didn't have to wrangle with my conscience about the expenditure. But if you travel a lot and have had the experience of your paddle breaking after air travel (very common unfortunately), then you'll see the value in having a top-flight paddle you can put in your hard luggage case, or as a carry-on.
Thanks. I will have a look at that paddle.
