Don't switch horses

I have been spending a fair amount of time on the various OSR/classic-gaming/DIY DnD sites lately.

If you want to see the ones I mean, OldSchoolJump is a veritable Decanter of Endless Linkage.
These have been giving me a lot of "grass is greener" feelings about my current 3.5 game.

I find the game I am running right now very frustrating. It means a lot to me and the players, but sometimes it feels like equal parts chore and challenge. I feel outmunchkinned by the party, thanks in no small part to the lazy-fair attitude I have taken towards the use of official supplements(spell compendium contains some gamebreakers).. and I have started to view a return to an old-school playstyle as the panacea to this. Manageable power levels, monsters that can effectively trample the players if not handled properly.
I find myself often looking forward to the next campaign, where I will run some mutated variety of OSRIC or Labyrinth Lord, or Microlite20.

It's not fair to my group, though. I get this. I know that devoting attention to the "next game" before finishing this one is a waste of energy.
When my current campaign is done with, I will take a nice holiday, slinging ten-siders to spend motes of essence, with someone else behind the shield.

I am looking forward to it, but it is important that I devote my energies to making the finale of my current game as good as I can.

One caveat, before I am called hypocrite-- I am going to run a one-off game using OSR with a module I recently purchased. Preptime is minimal and it is a very user-friendly module from what I have seen so far. So no rubbing my nose in this particular post when it is followed by after-action reports on a different game. Just don't.
