Leave the plate work to aterpster .. he knows all about that heavy stuff.
However, AFM/regulatory OEI limit generally is 15 degrees due to climb degradation. Company procedures may reduce this for specific escapes generally to constrain turn radius for threading one's way around the rocky bits.
For OEI - until one has a goodly speed margin and terrain is no longer a concern - more than 15 degrees is, in this ops engineer's view .. a tad silly.
