Depends on your plugged in situations as to what would work best for you, but when it comes to the sound from pickups I don't think you can beat K&K minis for a great acoustic sound with little fuss, and no clutter inside your guitar. (Greypicker, you have a guitar with a sound worth preserving plugged in, as i'm sure you'll agree.) I have fitted K&K minis in my Lowden O25, Lowden S10 and Fylde Oberon, and am about to fit them to my Fylde Ariel. The guitars each retain their individuality better with this set up than many other pickups I have tried.
Some folks feel K&K minis to be feedback prone, but I have no problem, perhaps because I play in relatively low volume situations and I rarely, if ever, use any monitoring either with church band, ceilidh band or fiddle/guitar, guitar/vocal combinations.
Much of the time I also use a K&K Pure XLR preamp for extra mid-range control - a very simple, quick and intuitive preamp to use. I also carry a Boss eq pedal as a backup which is also easy to use, not quite such a subtle rendition of the acoustic guitar sound, but fine for band use. I use instead a Baggs PADI in my church set up, because I can leave it there with my carefully twiddled default settings ready to go as the venue conditions are fairly constant. I find using the PADI in differing venues tricky as it takes me ages to get it right - too many things to fiddle with for a simple bloke, but good sound eventually.
I always feel that the Fishman soundhole pickups have a slightly "electric/metallic" sound to them. I know it can be minimised with careful eq, but these pickups don't do it for me, thouh many people really like them.
I did manage to get a reasonable Lowdenish sound with an active i-beam in my O25, but the K&K sound is so much more faithful to the acoustic sound to my ears.
