I am using the stock 6.5 sprint rom with cookie home tab mod for the sense UI
BE CAREFUL with your mods. some are not cross compatible. For example you can't use BG4ALL and Cookie 1.8.5 together since they conflict (cookie has it built in)
etc.. So keep an eye on what your installing. read up watch for compatibility issues and BACKUP BACKUP BACKUP because if you start messing around YOU WILL break it and have to hard reset it at least one time probable many times.
thats part of the fun don't worry about it just back up anything important
it would be nice to get a good list of "GOOD" games. while sure some games are user specific a good game is still a good game IE a game that is fast clean pretty IE nothing wrong with it etc.. and works well on the TP2 etc..
