by botch i mean fail, the old Lvl X tools are harder to create and item then the new ones of the same level. i beleive this to be down the the diffrence in stats. just to confirm though i'm not saying if you want success & HQ's throw your old tools away. it is still possable to HQ and make the same items as before with old tools but my observation is that it is a lot harder to do so.

what i posted before is just my experance and i know some others may disagree, but i thought the info may help the OP.
