Nobody can really say that 8/12 reps is for size and 1/5 reps is for strength etc. It depends on the individual. Everybody has a different makeup of fast and slow twitch muscle fibres so will respond differently.

I dont like high reps (except for squats ) i like to lift as heavy ass a weights as i can shift! So normally stick to sets of approx 5 reps. But thats just me

its trial and error im afraid, just like most stuff in this game!
