The fact all 3 gathering classes offer 4 T4 materia for completing story quests it's not that hard. Sell the T4's buy HQ lvl 60 gear and some T3's off what you made from the T4's/converting the SB'd gear from lvling. You literally only need 4 overmeld slots if you use all 3 T3's on the 100% slots of you gear. Once I had my botanist and miner stuff melded I was able to cap off red scrip in less than 2 days.
