As for "Kegler bowler", given earlier, some dictionaries online give 'kegler' as just meaning a bowler (tenpin or similar). But the Bowling Wiki kives a 'kegler' as a perfect game, 300 points, or 12 straight strikes.
So in this case, "kegler-bowler" would not be repetitive, using two words with the same meaning, but describing a bowler who is capable of (or has) managed to play a perfect game.
