Dropout types?

I'm in the early stages of ordering a custom ti frame, and uncertain on a couple areas.  For dropout type, can choose from four options- sliding adjustable, vertical, horizontal, or track.

Recommendations? Pros/cons?  I'm planning on running a 2X drivetrain if that makes a difference.

Is this for a disc brake or rim brake bike?  I would eliminate horizontal and track right away.  Vertical would really only be used for a QR bike; and if the are equating vertical with fixed thru-axle then I guess that'd be OK.  But sliding thru-axle dropouts seem to be all the rage these days.  You can fine tune geometry/tire clearance, convert to SS on the fly if you torch your RD, and run gears the rest of the time.  Some are even configurable between boost/non boost spacing.

what wheels and axle will you be using?  
do you ever want to run single speed? 
Are you running quick release?  Most everything these days is through axle...

Thanks! It'll be disc brakes and thru-axles.

Not sure on what wheels yet, but will be thru-axles. Doubt I'll run it as a single speed, but I suppose to keep options open, if the adjustable give that option without any significant downfall, might be the way to go.

If you're going with disc brake thru axle (good choice!) then I think sliding adjustable is absolutely your best bet.  Similar to a Trek Checkpoint or Salsa Woodsmoke, among others

The only downside I can think of is additional weight and complexity /cluttered appearance. Some seem to look a lot nicer than others.

what builder are you working with?
