Actually Jboots are not as fast as any level sow. However, as any non-selos/sow caster that has them will tell you, Jboots are "fast-enough" to keep you ahead of most mobs (espcially with jumping which is a trick I learned with my warrior).
That being said, I would prefer to be constantly ahead of any mob with selos than have to wonder. I have also heard that Run 3 is good enough to swarm some things. I haven't tried it though. Level 49 selos is great, I don't twist it, but just click it when I see it start blinking. Cake. 2.5 min of superspeed. I too use it with SS boots to pull over water. The two last the entire pull, it's great, I can worry about getting too close to mobs rather than twisting.
Oh and Shaitain, though I'm not on your server, you can always shoot me a cross-server tell (I'm on morrell-thule) if you have a question. I love helping folks.
