Thanks for all of the opinions on the subject, everyone. Honestly, I won't begin to claim that I'm the most experienced pilot around here (not even close). I've had my airplane ratings for nearly 15 years, but spent about 12 of those not flying airplanes. As such, I ask these questions in an attempt to improve my own technique in the future!
I suppose it's kind of hard to draw the line on these things. At the time my mindset involved knowing that the Seneca is a light twin, with a cruise speed that is probably close to double mine. Given that I was only midfield on the downwind at the time, I estimated that I'd possibly create a hazard if I had tried to fly the pattern in front of him (right of way issues be damned). At this time I can't recall if the Citabria had announced that he was in the pattern behind us yet or not; I may have already known he was there, but may not have.
Anyway, I doubt this was truly a four mile final on our part. It really didn't seem that I extended the downwind by even more than a minute, the winds were very light, and a C172 sure isn't a speed demon (again, perception and reality could have been a bit different).
I guess with more time and experience it will probably be easier to judge when I can squeak a landing in before another aircraft, but I took the "better safe than sorry" approach in this case (knowing that the other aircraft was already straight-in, and quite a bit faster than mine). The CFI with me also agreed with my suggestion to extend the downwind, though I know that doesn't necessarily mean it was either right or wrong to do so.

The only time I've seen much of an issue is when 15 is in use by everyone else and someone is doing an ILS approach to 33. Even then, most practice approaches end in a missed approach so as not to interfere with folks going the other direction.
I'm assuming, although you didn't say, Kev, that the Seneca was coming into 15 also, which would put him on the RNAV approach to 15. I don't think his call that he was 7 miles out was any indication that he was claiming the runway, just making a position report. I do the same thing when I'm on an instrument approach, real or practice, i.e., I announce a distance out so that others know I'm on the way in. As I get closer, I'll announce again, typically, but like most others, when I get close enough to actually be on a reasonable final, I'll try to slide into the pattern with everyone else.
I was up at KFNL on Tuesday as well, and had the exact experience you described (with a practice instrument approach coming in to 33 while a number of us were flying the pattern on 15. I certainly don't mean to say that the Seneca was trying to claim right-of-way on his approach today, but the easiest and smoothest thing to do seemed to be giving way to him (at least at the time). So, we did that, but apparently someone else was VERY unhappy with that choice. It seems that if you try to make someone happy you're bound to piss someone else off in this game!
Admittedly, most of my flying (in the past and recently) has been at Class D airports. I currently fly out of KBJC, and have flown out of KAPA (in helicopters), and originally learned at KOSU. All of those places are Class D, and in the ones I've flown regularly in fixed-wing aircraft the most common thing I experienced was a controller asking downwind traffic to extend their downwind. I flew into a lot of non-towered fields when I was in Ohio, but none of those seemed particularly busy when compared to the ones I've been to along the Front Range in Colorado (Ohio has a lot more airports, which could have something to do with that).
Anyway, thanks for the thoughts and insight from everyone who has responded so far!
