Drum Maps - Which default drum maps are we unlikely to use?

Sonar X1/X2 comes with a bunch of drum maps. It's a pain to scroll through the list when selecting a drum map, so I'd like to move some of them into a zip.

The question is: which drum maps are for hardware, or for soft synths we are unlikely to use?

I have Komplete 8, so would like to keep the Native Instruments maps, plus any maps for kits that come with Sonar.

I'm guessing we should keep these:
- Beatscape Pad Triggers.map
- Blank Map.map
- Default.map
- DimensionPro Drums.map
- GM*.map -- since these are general midi, right?
- NI -- for those of us with Komplete 8

and maybe these:
- Inverted Map.map -- what is this?
- Numbers (Pass Thru).map -- what is this?
- Pass Thru Map.map -- what is this?
- Pitches (Pass Thru).map -- what is this?
- Session Drummer 2.map -- is this used by Session Drummer 3?
- Session Drummer 2 - Default.map
- Studio Instruments - Drums.map -- not sure about this
- RXP*.map -- are these for the REX player included with Sonar?

But what about the ones starting with:
- AKAI
- Alesis
- BFD
- DR-808
- Edirol
- E-MU
- Ensoniq
- GeneralMusic
- GS
- Kawai
- Korg
- Kurzweil
- Novation
- Purfffect
- Roland -- are some of these used by Sonar kits?
- Sonic Implants
- Superior Drummer
- Technics
- XG
- Yamaha

Which of those are for hardware?
Which are for soft synths not included in Komplete 8 or Sonar X2?

My question is which ones are unlikely to be used (and therefore can be moved to a different folder without affecting NI synths or Sonar's included synths).
