Were it me, I would go for DI2 + Hydro disc. - To get rid of the mechanical cables and get max performing gear shifts and braking.
That's what I did, no more cable issues for me! Plus, the shifters are great, perfect form factor, imo. It's crazy how much smaller they are without the mechanical pieces, always thought the big shifters were due more to the hydro brakes, apparently not. lol
