I shoot the Exact express 7.9gr and have for a long time.
Andy Gillot won the GP series wih pellets i sold him, they were the same pellets i cleared 4 courses with and won the 2008 UKAHFT. I find that they are more consistant for weight spread out of the tin and take less wind, even at longer ranges. The only negative i've found is that my sponsored Daystate does not seem to like them.
I'm bringing 100 tins back from Holland in a few weeks along with a load of 4.52 8.44's....and i'll get more around the June time.
