you're missing out on the majority of the best pad content out there, let me suggest you some new banger packs! Also, the best pad experience comes with simply love for sm5.
Monstercat minipack, fraxtil's beast beats, fraxtil's arrow arrangements, dl them here:
https://fra.xtil.net/simfiles/ (you will also find some stamina files but they might be overkill at this point)
trancemania 3:

(if you like long streamy files with multiple difficulties you should look for 1 & 2)

You're missing out also a lot of files from mudkyp, mootz, joe, sudziosis, the latest valex and talon packs and more but i don't know if you're willing to download like 4 gigs of stuff all at the same time so up to you.
www.divinelegy.com,
www.r21freak.com and the group "DDR + ITG players" on facebook are the best places to look for and ask for pad files.
If you're feeling REALLY BRAVE here is a community dropbox with basically ANY pad pack ever made
