WGT should put attributes next to those club sets. I checked The MK3 and MK4 sets but it only shows the price and what the set icludes. My advice F would be to play in the Casablanca room where you get up to 10000 coins and then try them out.
Its a shame that we can't use these coins for other brands as well. A level 80 set is 4 million coins ( again no stats) which seems a bit daft IMO. Hopefully WGT comes up with a better idea on how to use these coins.
