Man, do I hear ya!!
I have told numerous people that what my Ornate ate in the first two years could keep a PAIR of bps going for 14 years... if they never skipped a meal.
I have large constrictors as well, and they aren't ever going to see a rack or a tub or even one of those Sentec thingies... I don't think they're big enough for a burm or tic.
