All of the above, but mostly one-piece rods, unless I'm really tight for space. I prefer plain steel rods from the HW store, the SS ones I have don't seem as stiff. 36" x 1/8", 48" x 3/16", 60" x 1/4" - store them in a piece of PVC, steel wool and oil after every use. For NRC, I fly nearly everything off a piston with no tower, using 36" long aluminum rods and 34" piston tubes. Egg Lofters I'll use a tower and piston combo. Lastly, I occasionally use a 60” mini rail if I want to completely eliminate rod whip.
