but it almost definitely can be made to work

as for your 105 shifters
hmm that's odd

I had dt shifters before
that rested about thirty degrees into its travel
to make it easier to shift both levers with one hand
so maybe it is something like that cutting into the cable pull
Yeah, I didn't think it would be that dramatic either. I've gotten older XT derailleurs to work with barcons on a triple. For some reason, the LX low clamp derailleur with the DT shifters needs a lot of lever throw (~80%) for my double. It works, but is not ideal. I don't have experience with indexed Shimano bar ends, can they shift mountain and road front derailleurs equally well? The other relevant question is whether they use a standard 2:1 ratio or Dynasys ratios for 10 speed rear shifting. I've heard they use standard ratios.

bar end shifters are
never indexed for fds
theyre always friction

as for rear
bar end shifters are intended as road components
and dyna sys is only made in mtb components
so i assume all bar end indexed shifters are non dyna sys

My Experience with Shimano interchangeability:
Rear:
10 speed road shifters should be used with 9 or 10 speed road derailleurs or 9-speed MTB der's.
10-speed road shifters can index 9-speed cassettes well with the "alternate cable routing" trick.
Oddball derailleurs: 8-speed Dura Ace and 10-speed (Dyna-sys) MTB.
Front:
Indexed shifting should stay within groups- road with road and MTB with MTB. 2-chainring with 2-chainring and 3-chainring with 3-chainring.
In general front bar ends are friction rather than indexed, thus work with most any derailleur.

I saw this in another forum thread which could help adapting shifters to cassettes:
