Ok, I've gone through Winner's Path four times and caught three Magicarp, two Horsea, four Duskull, two Beldon and one Munchlax. The Munchlax are very rare, the rarest pokemon so far I've looked for in the pokewalker. I've mostly found berries, but did get a White Herb. I'm only 3,000 watts short of opening up Sinnoh Field, so I should be able to get more items here before the end of next week.
