Steve I'm sure you beat me, my last LA Marathon on March 26, 2011 I ran with 5 hrs, 28 min, 15 seconds, so with your long kickers you should let me eat dust.
Yeah check out the Ergo, have some misgivings about the Aero, pm me if you want the scoop, don't want to post public.
I have the same setup on my '16 F6B Deluxe and like them a lot. I have a shorter inseam (29.5") so having the pegs closer makes for a nice riding position when compared to other options that put the peg further fwd.
When (if?) you install them, highly suggest you tilt the arm/pivot point piece "up" (i.e., towards the sky) and then use the set-screw (hex head) on the bottom to cinch down the assembly. Be sure to insert the hard plastic inserts in correctly. Note: I put one wrap of Gorilla Tape around the inserts to make them snug-up nice and tight. This will help with clearance when (if?) you lean the bike over during hard/tight turns.
