I personally prefer 1.36kg, but that's borne out of a combination of mild OCD and the fact that it keeps things inline with international competitors.

That said, the FW limit went up to 13.6kg to bring it inline internationally allowing for easy inter-continental battles, but how many of us have gone to the US/Aus with our feathers, or vice-versa since then? Also makes sense to make such changes while existing robots are few and far between, so if the limit is 1.5kg, then I'll build to that
