@FitScience , This is an honest question. Why do you feel the need to upgrade it right away? Why not get it first, enjoy it for a while, and only consider upgrades later if you really fall in love with it?
I’ve upgraded most of my reps over time, some with gen parts, others with higher-end aftermarket bits. But truth be told, not every one of them ended up being the one. And selling a modded rep can be a pain, since not every buyer will appreciate or even want the upgrades. You’re left with a pricier rep you don’t actually love.
So my advice is to wear it first and mod later. For Daytonas, Clean is a safe bet. Their crystals are consistently subpar, not just on the Datos but across the board. Still, the pros outweigh the cons. Even with weak crystal game, they’re solid reps. You won't go wrong with Clean.
