Re: To Port or not to Port...
Playing at home just go no port, unless you like really punchy dead bass drums, then they help a bit. I ported my kit because I mic a lot and like the sound when the mic is all up in there. However I use a kickport which gives back some of the unported rebound and sound. I definitely recommend for anyone with a ported reso, though it does react differently on every drum and some get little to no benefit.
My basic advice for anyone, don't port unless you mic your gigs. If you do, try a kickport, one of the few gimmicky products I truly was impressed with, made my kit sound like 1 instrument instead of a bunch of drums.
