Changing the end caps, easier than you think. It looks exactly like it is. Undo knot, pull through, change end cap, thread bungee back through sail and washer, tie up. At this point you can adjust the tension. I've worn out 2 bridles and 4 end caps on my B2, but it sees the most air and is the one that i try most new tricks out on.
A standard 1.5 is the best pair to a vented, their wind range crosses over. I think most people would suggest to get it with Black Race Rods, I would too.
Hope that helps.
