Personally, I'm happy with a 5IV spread. It doesn't have to be perfect, but if I can get 5IVs in something, I can then breed for 6IVs later one at a time and go in Dex order.
But that said, I am still working on getting 18 more species in the Safari. Had a better day today than expected on my Safari Dex, stumbling last nite upon someone with BOTH missing Flying types, then went Togepi hunting this morning and ended up at Reddit. Reddit guy hasn't added me yet, but I don't care; I checked someone's Safari at Neoseeker and the first thing I saw was Togepi. Later, the female hunt was complete (12.5% is LONG, I've done it with Eevee, starters, the Pan trio, and more). Fairy complete! Riolu came along, also rare in females, and I completed that female collection! I then looked at the Safari thread and found Muk and Garbodor in a Safari; I still had a Garbodor Safari, but no HAs, and Muk was the only missing species, so that is now complete!
My Safari search is down to two Normal types (I have HA Audino, but want to catch a trio the same day, so need a new Audino Safari among that, Dunsparce too), 3 Dark types (have Absol and Mightyena on add requests, missing Inkay), two Electric types (Electrode and Galventula, the former missing HA and the latter only caught in HA, again needing fresh sets), two Fighting (Mankey and Meditite, one I think in hand again but missing HAs), four Grass types (these keep eluding me, I'll be using the Safari list soon), Duosion for Psychic (going to clear this ASAP), two Rock (Rhydon and Nosepass, I've seen both in Safaris but never get added), and Bronzong for Steel (asked someone at GameFAQs, don't expect to ever hear from him), and Poliwhirl for Water (asked someone here, awaiting response). And I'm done. :)
