Thanks, you're a pro and it's nice to learn from one!
So, revising the previous description I posted:
My DT mtb wheels, also built by Garcia, have the same orientation as SL's wheels, trailing spokes heads-out.
However, my Dave Thomas Speed Dream road wheels are the opposite, trailing spokes heads-in.
My FRM road wheels (for sale BTW) are the opposite, trailing spokes heads-in.
My Spada Stiletto-Lights (for sale BTW) are straight-pull, but the trailing spoke is to the inside, so if j-bend the trailing spokes would be heads-in.
I must admit the debate over which method is "better" (if one method is such) is still confusing to me though...it almost seems as if it's a philosophical difference as well as technical, and even somewhat dependent on the particular hubs, spokes and desired qualities, as opposed to being an absolute.
