I just seem to have fantastic luck with the Bulbasaur line. I already have a 100% IV Venusaur with the optimal offensive moveset (Vine Whip/Petal Blizzard). I also have a 93.3% IV Venusaur with the best defensive moveset (Razor Leaf/Sludge Bomb). Now this newest Bulbsaur is near perfect at 97.8% (14/15/15).
As for the Squirtle, I've had my luck with high IV Squirtle, but they all ended up as Blastoise with inferior movesets. The last one I caught wild had a 95.6% rating (15/13/15), but ended up with Bite/Ice Beam. This new Squirtle is at 93.3% (13/14/15), so I'm crossing my fingers for good ol' Hydro Pump this time.
