Which type of enlarger light source would be recommended to print negatives which are developed slightly thinner so they scan well? Diffuser? Cold light? Condenser?

I'm finally going to have some space for a darkroom. I mostly only shoot 6x6 and 35mm.
I have an omega d2 and a b22 but both may be incomplete in one way or another so just buying something else may be cheaper. I'd also be willing to change the head on either. I'm eyeing focomats but don't know if I'll have the $$$
