Runway lengths

Thought I post this, since I'm often a little puzzled, especially the more I practise landings on medium airports with traditional commercial planes.Let's take for instance GCRR (Lanzarote) or the probably better known KMDW (Midway).Both have long enough runways to let me get even a mid-weighted 747 in the air.So, the takeoffs are not the problem here (though I admit that I might be flying unrealistically at times, when I have the impression the main gear would hit that fence in the next couple of seconds during roration ;-) ). It's the landings which make me kind of uncertain and think I wouldn't probably try this in real life:I foremost need to say that for the fun of it, during the last months I got used to do purely hand flown visual approaches without any ILS (and often even VASI etc.) guidance whatsoever. The aircraft I'm talking about here are jet airliners the size and weight of e.g 737NGs and MD80s.So, when doing my landings, everything works just fine, I touch down, roll out, and leave the runway. Nothing spectacular (at least for my passengers) you might think.Now, let's have a closer look what happens in detail:Having established the speed of choice, I get 'her' (whatever 'she' is, let's assume the MDMax MD-80 here which I recently used) on a reasonable glide path.When I'm lucky ;-) I even manage to deploy the flaps to the setting which I think is the best for the runway lengths mentioned above before touching down (mostly full flaps).I cross the threshold at a reasonable height (after the usual struggle with sink rate, trying to stay on centerline and not letting speed go too high or below Vref+some margin - not to forget keeping the engine RPM high enough for a GA, of course), aiming for the 1000ft marker, and settle onto the runway somewhere near the aiming point.Now comes the phase which really makes me doubt whether it could be I'm doing something wrong:After the spoilers deploy (often I forget to arm them, and some planes like the DF727 I guess have no arming mode at all, so I get them out manually) and the nose gear gently touches down (not too fast, not too slow), I deploy the spoilers to full because of the limited runway distance left (I usually don't activate reversers before nose gear touchdown in such relatively small sized planes, they don't have rudders the size of a 747 and maybe I would get troubles with directional control doing otherwise).And the aircraft drives down the runway, and it continues to do so, that I think it would never come to a stop. To avoid brake overheat (which is an issue at least with the MDMax), I start to engage them at 80kts max only.Okay, in case of KMDW, the fence approaches with incredible speed while I'm still at 100kts, the plane drives down like a racing car and I need to suppress the urge to use full brakes prematurely.Then, suddenly speed drops off and finally I'm at 80, full brakes, and at approx. 60kts I stow the reversers.Where I am now? Well, the aircraft has already left the runway: if you happen to know KMDW (I use FlyTampa's incredible add-on), you know that after the runways comes a relatively spacy taxi area - that's where I am at this point.Of course, I can do a 'more precise approach' and touch down as soon as possible, what gives me more room for bleeding off speed.But I have two problems with either approach to the issue: trying to touch down early lets me come in very low, I risk scratching the roofs of the houses around KMDW. A steeper approach I guess wouldn't be an alternative since I would need to reduce the abnormal sink rate at the cost of increased flare distance. And touching down 'normally' causes me the troubles I have.Because of the dangerous character of my landings at those mid-sized airports, I'd be probably scared to the bones in real life, that's why I cannot imagine doing this with a real aircraft.On the other hand, such planes are flown in and out of such airports daily, so the airports must be suitable for these aircraft.Is this normal what I encounter?Andreas
