while i understand yer reasoning for doing this and agree that it probably will give you more confidence while doing tougher moves, it sounds like taking an unnecessary risk, imho.
i agree with this 100%. it not enough to know how to just place gear, but to be able to place good gear. placing gear is more than just the gear itself - its about the rock quality, too, and the orientation of the piece... good gear you do not need to worry about trusting.
