I tried Gruss but found that my computer slowed a lot, once excel tasks grew intense. BA is faultless at excel integration. You can have multiple spreadsheets feeding a pre programmed schedule of events. You can have Aussie Rules each game of the day, Rugby League, Soccer, Greyhounds, Trots and Gallops all with different formulas to either Back, Lay or Trade. All independent but the integration is seamless. Not sure if Gruss can handle this? Something to consider.
