I took this set in to Golf Town over the weekend and had everything checked out. They ended up resetting all the lofts and lies back to standard (they were way out of whack) and verifying all the lengths as well. We then went through a 'mini-fitting' to determine if I could just use the standard shaft lengths (which I can) and also found that the DGS300 shafts were just fine for me. The only real deviation was I had to have them all bent 2 degrees upright.
I took them all to the simulator at my local golf dome/range and gave them a good workout to see how they hit compared to before. I also took my previous irons (CG Golds) to compare. I have to say the shot pattern was very tight compared to before adjustment and even compared to my CG Golds. I am a happy camper and can't wait for the grass ranges to finally open! 
Oh it was also recommended that I upgrade to midsize grips as the standards are a little bit too small for me. But I'm going to hold off on that I think (I'm used to standard grips at this point). So for about $185CAD all-in I got some pretty nice irons that are even fit to me!
Thanks for the great advice guys!
