I personally am using the 180>200 augmented main hands on my DoH's but using crafted HQ 195's for offhands. I see no reason to invest the gil in MH for time being personally because I can do 3* without even melding the MH/OH or even chest pieces. Whether I switch the MH from 200 to crafted 195 will depend on what the next level of recipes requires but for the time being I would rather save my gil and not waste it on materia I might not even need. The only reason I went with 195 for offhand is because takes way too long to save up enough red scrips to buy all the OH tools but the MH tools only require blue scrip so that's fine.
