I'm using the weights:
WD 7.536
STR 1.000
CRT 0.167
DTR 0.227
SS 0.157

The CRT is based on an average of "DK-only" and "DK+Bootshine" values. The general damage formulas are based on valk's. There's currently some discussion re-evaluating the way DTR is handled in valk's formulas (with signs pointing to DTR being slightly better than the formula reflects).

I basically slotted all the highest "weight" items, then switched them one at a time to the "accuracy" version of the items until I hit >470. The result is 473 in this case. I switched them in order of "least weight lost per point of accuracy".
