DB/SR does indeed look sweet, and is extremely fun to play. The /SR effects are the least obnoxious of any Scrapper secondary, they are nearly invisible, even on a character of average size. Basically it's faint white swirly things around your character. The Combat Jumping effects are more noticeable. Even if you want to customize the effects, you should roll him now, to take advantage of the free respec that they seem to give out with every issue launch.
It's also one of the easiest secondaries to play, since you just turn on your toggles, put Practiced Brawler on auto-fire, and go kill. All tier 9s have a long recharge, so don't let that influence your decision.

Once you can soft cap /sr, you won't even need Elude, so it's vastly a non-issue. /sr as a whole starts slow, but has as good of end game potential as pretty much anything. It's currently my favorite secondary for scrappers.
I have a DB/SR and I think it is one of the most visually appealing power combos for scrappers. Don't sweat about Elude, by the time you can choose it you may very well not even need it, as soft-capping defense with IOs makes it (almost) useless. And the great news is that you can soft-cap SR for very, very little money.
On the flipside, be aware that if you want to make the most out of DBs AoE potential, you probably want seven of the nine attacks, and you also want 8 of the 9 powers in SR. You will probably want stamina, as you have no end recovery powers, and the fighting pool is very, very attractive for SRs. You might want Aid Self too, to not rely on green insps when an enemy gets lucky and knocks off two thirds of your hitpoints in one swing (it doesn't happen often, but it does happen). All in all, the build is VERY tight. You can loosen it up somewhat by taking just Blinding Feint and the attacks needed for the Attack Vitals combo, as anything else is pretty much added AoE pizzazz and thus (for some) optional.
I have a question, I heard somewhere that a Dual Blades/Super Reflexes scrapper looks almost like a dancer with the dodges from SR and the movement of the blades in DB, and I plan to roll one but, how well does SR play? I already like the powers of DB (a cone attack that is unmatched except for the tier 9 which is also a cone, the combo system... all of it rocks.) but have no idea about SR. I like the power quickness but the long recharge on elude is kinda scary (never used a t9 defensive power.) One more thing, how does the fx effects look, I might wait untill I16 goes live if the effects look wierd, but if not I would roll him before (What would be some cool colors to put on SR, the fx will determine his roll time.)
Those are my questions, and thanks for any and all replies.
