jannine around 45
sabrina 50-55
blaine 55-60
giovannie 60+ (if you get outspeed by mewtwo,get a pokemon with paralyse move-thunder wave,stun spore)..best would be megnamite lvl 13+ with sturdy,so you wont get 1 hit and can slow mewtwo down with thunder wave
At 1st when i made the guide,the pictures were big, but then they just went to small version for some weird reason :S
You can click the pic though to make it bigger in next tab :)
i prefer surfing on route 24 (north of cerulean city), only krabby and goldeen.
tohjo falls is also nice (goldeen and seaking only) but its annoying to go heal back to town to recover PPs. :S
