I must say it is pretty tough getting the 'drums sound' down, be it in a recording or studio environment.
In a recording setting, the sound engineer is a key player especially if he is one who can double as a producer. His knowledge of mics, white noise etc is crucial plus he has to factor in aspects like mixdown& even mastering.
Using the 2 quoted examples here namely Leonard Soosay& Lordie's band:
Leonard is one heck of an engineer/producer. From his Myx studio days to Mastering Suite& eventually to Snakeweed. He has done recordings for a wide genre of music& catered to the equally varied idiosyncrasies of the musicians that come with them. You should give him some serious consideration.
As for Lordie's band or rather brand of music. In my opinion, genres as such is the most challenging when it comes to nailing the drum sound. Some folks may say it's all about playing fast ( see brutal ), hard etc but to me it's also about getting the right overall balance. I must say, the end product for his band is pretty impressive.
Most people would wanna go all out when it comes to recordings especially when they have the budget for it so in that regards the work starts from research, which is basically what you're doing here& kudos to you.
There are a number of exprienced engineers, musicians on board& I hope when the dust settles, you're that much closer to finding what you're looking for.
As for rehearsals. that's tricky. Having your own snare, cymbals may help you or at least make up for what would be lacking. Drumsets in studios go through a lot of pounding& at times even abuse so to find one that sound good today would probably be crap some time down the road.
Don't be discouraged, I've had studio time where the drums are crap but we use those times as basic structuring sessions. When we're ready& have made some progress with some songs, we'd head out to a studio with better skins.
Good luck brutha.
