If u update to zvh u don't have to stay on the cruddy stock flash your mom rom and it has no bugs and runs way smooother than a zvd baseband so update to zvh
afaik most people on this forum who are currently using zvd baseband aren't running the "cruddy stock" rom
both zvh & zvd have solid custom roms. i personally run thekraven's cm7 on zvd baseband, though i have heard good things about your mom rom. i'm glad to hear that you're enjoying it.
Your mom rom is awesome but if you are using cm7 why don't you update to the real gingerbread then flash your mom if you do decide to keep your zvd radio i reccomend reborn rom thats i good rom a ran that rom before flashing to zvh
