First of all, congratulations for this guide, I think it's very complete and useful for a "newbie in breeding" as I am.
I have always been more like the 'Example Understanding' kind of person, so if you could just answer my doubt, I think I'll get all clear:
I have this mareep 17/5/30/29/5/31, I don't care about the attack (5) and I'm fine with the HP(17), but I would like a 25+ Sp.Def.
If I use a brace on the Speed for the next breeding (so 31 is garanteed), do I have to get a 17+/X/30/29/25+/X Ditto (for example) where X are the values I don't care (as I don't need attack and Speed will be transfered from the Mareep)? Obviously putting a Sp.Def Brace on the Ditto too.
Thanks
