dusktrader, if you get interested in tick data again, Dukascopy has a comprehensive tick archive back to 2007 for a lot of pairs. Enter `php dukascopy' in google, and click on the first link to obtain software needed to download the data. It is updated every hour.

I suppose I'm glad not to be the only one messing with data here and there.

Although, I've so far used tick data only to synthesize various interesting bar formations (constant range bars, renko, median renko). And only played with EUR/USD, which is currently 844MB (2007-2013) heavily compressed, just to give you an idea of how much space tick data requires.
