Your STR is very low. In order to reach Garuda's lofty cap of ~358 STR, you will need to invest in STR-melded hands. Swapping STR into accessories (18, 4) and body (10 or 20) would leave you 18-28 STR short based on what you're wearing now. Melding even more STR means liberating accessory slots for INT, ACC and ATK--or, in your case, liberating your midsection.
With that in mind, it is better to use Tricorne for the 5 STR in addition to 35INT--both of which are uncapped--as the difference of 5STR/15INT will supersede the ATK/crit on eyepatch.
When dealing with MNK damage stats always aim to cap STR first. Follow up with INT to cap, then ATK everywhere else. Add ACC whenever necessary.
