Here's some advice when looking for good frames. You should always try to hit frames with power items and an everstone equipped, always re-save a couple of times to see what the NPC's can give you. If you hit a good frame with a Power Item you could consider breeding on that seed even if it's a bit hard to hit(you can check frame independent of seed btw). If you have a good seed but crap frames you can try using the Churine and Chiiramii to time your pick-up, like you were the first to suggest =p
