Thanks for your answer. Lately I have been mostly playing 22" bass drums (Tamburo stave, 16" and 18" deep), and I like very much their power and their fullness. The last 20" bass drum I played on a regular basis was a Slingerland in the late seventies / early eighties (sic!), and I barely remember how it sounded. What I would like to know is how powerful and full you consider your 20", and how much difference you see - if any - with a 22".
This is obviously just my opinion and not fact.
I honestly have always felt the 20" is the most versatile of all sizes. It can go small, it can go big. It can provide a heck of a punch or it can provide am open round sound. I've had the 20" tuned in both directions and it delivers in every and all aspect (on my terms) but mostly I keep as an open round sound. While it can (and has) been done for many, many years, I don't think a 22" does the open thing quite as well. That said, I did keep my 22" RC wide open and it did work. I just don't think it does it quite as well as the 20".
The combo I enjoy most is a coated EQ3 batter with the stock reso front head. Nothing else inside the drum. I use a Gary Chaffee bd muffler on the front reso with only one of the two pads barely touching the head to help with the sustain control for finishing touch. The other pad is lifted away from the head entirely.
I have not yet recorded the drum either closely mic'd or otherwise so I can not provide much help on that.
