So, i'm looking at getting some reprolabels for the first time...namely to put an autobot symbol on "Defender's" chest and on iGear's base. What background should I get? Clear/white/silver/mirror...are they all equally good stickers? What kind of sticker do most figures take, since I'll have a ton extra to use. Any other recommendations as far as 'must have sets'? I'm a sticker noob and honestly don't like to put them on...too worried about misaligning them.
