RE #1 Get the largest diameter you can. How low the trap works is determined by how large the internal arispace is. However, in the case of these, which have way too high of a density, it may not track like it is suppossed to as closely.RE #2 Either 40 or 50 mm, 50 if possible.
RE #3 The lowest density you can. The 40 kg/m3 is still too dense for proper resistive action, and even with the proper density, pre-formed fiberglass just does not seem to work as well as non-resin bonded fiberglass that has been compressed.
Most of these are in the upper density ranges, the lowest I have seen is around 80 kg/m3.
Be sure to get the plain kind, any of the coverings is likely to just make things even less optimal.
If you wrap the outside with polyester batting, and then place some thin/limp plastic over only one half of the cylinder, you can then tune the acoustics somehwat (less than with the ASC clones, but still some), and this may help optimize them a bit more. The poly batting will help get some of the upper midrange and HF absorption back that the high density snap-on pipes do not naturally possess.
I still do not recommend spending your time on these, but since you can get them cheaply, it IS your time to spend.
