Yep, there's a suggest improvement to GC, as mentioned in my review(s), use the KR style cartridge condoms on the end. It would suck to have a stockpile and have them be dried out in a few months..although the boxes claim good for 12 months on them.
The battery holes - yep, been covered, all recent KR batteries I've seen have 2 holes on the batteries, not 4. The GC carts don't *have* any holes, so I suspect it's about the hole placement itself when using KR batteries, but don't have a 4 hole KR battery (out of 10 or so) to compare to.
