We've played both recently and to be honest I was a lot more impressed with Cas, I thought they beat us quite comfortably and we did rather well to keep it close but there was no real time in the game when I thought we could actually win it. However when we played Widnes it was touch and go all the way and you could say that we were unfortunate not to get anything out of it. So by that reasoning I've got to go for Cas, but the form book is often thrown out the window in playoff games. To be honest I'm not that bothered either, I think its all set up for these two to meet in the final, as I expect whoever comes through a tough game on Sunday to still be feeling the effects next Thursday night.
