Part of me is like for the FFX run should I grind It out, or kinda run through and see how quickly I can beat it lol.

I think grinding is required to beat jecht (if you only do storyline and no sidequests/summons)

Not sure if I can "Mix" enough to get through it. But, once I get to the end I can grind no problem. Just curisou if I can blow the first 7-10 hours without grinding. I usually grind early

Ive found the best grindspot midgame is to be on the highbridge before u fight seymour 2nd time (sadly kimhari gets left behind)

Then zanakard ruins when closer to the end(inside the dome b4 yunalesca)

I think if you grab the right shit to mix you should be fine.
also about blitzball im pretty sure if you set it up right theres a way to just sit in your back half and you wont get rushed

Really? Ill have to check that out lol.

Zanarkand is a place I usually do and then also some cave until the Marlboro kills me haha.

Which cave though? U mean omega?

it's been along time since i played it or watched anyone but if i remember right, from the chocobo game after unlocking the 0 second race you can get the items needed for mixing the max hp and damage mixes there.

I think so. At work atm, so I cant double check. But Omega sounds righ. I just know Ive been wrecked by Marlboros to many times after grinding and not saving.
