If you're mass tabling HEM is a must, Ive always used HEM so got HEM2, no idea really about functionality of PT4.  At this point imo SS is just overkill, its fun to use, but definitely not necessary and is too large a chunk of BR at micros, just use OPR and your 5 free searches.

Those 3+rs are an amazing starting spot, train one well for MTTs and have a lot of value, especially in off-peak hours (even though they load slowly).

Im new to RIO, and so don't have any immediate recomendations for 180 mans, although I think Sam Grafton's 22c vids are solid, and its a tournament that provides a lot of varying spots w/ an interesting mix of reg and fish play.

Thank you very much, i will try to buy the Hm2 and i will take a look at the vids of Sam.
