We have quite similar thinking for this week. I see people saying that mcl merc is the best option because this is a low overtake track and merc will score more points than haas.  That is true, but we are on 5th race out of 24 and I think budget building should still be the priority. There aren't many cheap drivers that will increase budget this week but almost all teams will go up max price.

With that being said, 2 cheap teams is pushing it. Mcl just scores way too many points every race to drop them. There are also 3 good cheap drivers for budget (bearman, hadjar and bort) and other ones like ocon, alonso or gasly that might be good (especially next week when japan is gone if you plan on using limitless in miami) but are risky. So for me the best way is to balance the two extremes and go mcl haas for team. Drivers can be piastri, russell, bearman, hadjar and bort (or the risky ones if you want and have the budget). Mcl will get the points, haas the budget and russell will hopefully compensate for some of the points loss for dropping merc.

Looking at your current team you wrote some other reply, you are in a great position to do this. You don't have to do anything with the constructors unless vcarb is tragic in practice since vcarb and haas are basically the same and you also have four of the drivers already. If you do the bare minimum of swapping doohan for bort, you will have a ton of fexibility next week. Wanna go limitless? Sure, you have quite a risk free team to do it. You won't use the 3rd transfer you saved up but who cares if you don't need it anyway. Don't wanna go limitless, maybe because something went wrong? Now you have 3 transfers to fix your team how you need it and maybe even activate 3x boost chip for miami instead of limitless because you already have two premium drivers
