I'm looking to get my hold 'em game back up to a decent level. I haven't played any hold 'em cash or tournaments for almost 5 years.

A lot has changed obviously and I have never worked with all the hold 'em tools except ppt. Should I dive immediately into piosolver or some of the other tools? Not sure what my best approach should be. There aren't many transitioning from plo to hold 'em vids :). So which ones would be most usefull?
