Personally, I wouldn't ever want to go back to DT shifting. Sounds like you're going down another path anyway, but I would definitely recommend trying out a DT bike before you change to it on your bike. I tried a DT bike last year for the first time in decades, and I just plain hated it. I was good at it back in the day, but I really didn't want to relearn the skill.
There was a thread on here a few months back where someone was trying to argue that DT shifting was due for a comeback, and anyone who dard disagree was subjected to a barrage of "your not a real bicyclist" type nonsense.
I'm all for people who like it using it, I just don't think there are many such people left.
