I'd definitely opt for those long slivers/wedges over some kind of filler. Bona do acrylic fillers that come in a range of colours to match different woods. They remain flexible so while that's good for allowing movement, in any large cracks they'll be liable to damage. And any filler that sets hard will crack and fall out in big gaps. I used the Bona stuff on the very minor gaps I had ( < 1mm) and although I didn't get the colour spot on, I was happy with the results.
Dredging up floor chat again. I ended up removing all the carpet and the floor isn't too bad, I need to replace a few boards but I kind of expected that.
Does anyone recommend filling, or using something else to fill the gaps between floorboards? I wasn't thinking filler but more something of those 'V' shaped strips that fill the gap.
