Sounds like you are on the right track Spence though a sit on top might suit you better? More comfort and ease of movement. A pfd is a must! I carry a small air horn inside the pocket of mine in case of emergency. Its small I don't even know its there! Fish in it a couple of times and figure out where you might like the rod holder but generally they will be forward of you and within arms reach!
Sounds like you will do fine Spence! Welcome to join the yak rats on a day trip anytime!
