What size(color) FFG sleeves would I use for:

1. Ticket to Ride 1910 Expansion
2. Ticket to Ride Europe (may be the same as above, have to check)
3. Small World Tales and Legends (Large format cards)
4. Memoir '44

Thanks in advance!

What about the game Shadows over Camelot? My cards for that game are getting marked and worn

Just in case you're still wondering (probably not), M44 takes the FFG Purple sleeves (it mentions BattleLore as an example).

I use the American sized (Green) for Ticket to Ride 1910 and marklin. They fit great.
