So, any set of DDT that do you recommend for my case (or another better brand)?
DR DDTs are a good option as long as you don't mind stainless steel rounds as they're specifically designed for down-tuning.
The 4-string 65-85-105-125 set is good for B-E-A-D, but for A-E-A-D, you might want something a bit heavier for the A. They do come in a factory 5-string set with a 130, (45)-65-85-105-130 (DDT5-130), if you want to start there.
If you prefer nickel over stainless steel, DR Nickel Lo-Riders come in the same gauges as a 5-string set, (45)-65-85-105-130 (NMH5-130).
If you find the 130 too loose and floppy in A, the DDTs do come in 135 and 145, which can be ordered as singles.
