Time to Give Tactics a Break? (Updated)

I think it may be about time to switch to strategy and/or endgame study in order to get those aspects of my game up to the same level that the tactical aspect is currently at. I'm finding my play to be extremely solid lately in regards to tactics. The games that I am losing are being lost in either closed or strategic positions or in the endgame. It's rare for me to lose a game on tactical grounds anymore...at least at this level of play.

Using today's G/20 game that I played against a 2045-rated player on PlayChess as an example, I played a tactically sound game (with the exception of the last 6-7 moves which were played under extreme time pressure,) but in the middlegame started to lose ground strategically. I'm thinking that once I finish Tactics Module-3 in PCT (I'm about halfway done,) I'll move into another area of study for a while. I'd greatly appreciate any thoughts both on the plan in general and in my assessment of the game:

UPDATE -- The flip-side of the coin is that I have been seeing significant improvement in my playing strength and rating lately due entirely to tactical training. So should I just continue doing what has been working until I start to see diminishing returns and only THEN move onto endgame and strategy study? I obviously want the most bang for my study-time "buck" here.
