I have nothing against the duo cards. My main issue with them is that they don't really work for me. Usually the costumes are a bit naff.
The main problem is that Totem and the girls never really knew what a duo card in VGHD was supposed to be and how it would work. They couldn't work out if it was just supposed to be two girls frolicking about or a weak attempt at lesbianism. In my view, most are quite dull, except for the odd isolated top notch clip.
I certainly wouldn't say they were sickening, but then again I like DB.
Yes, you will find duo cards with lesbian activity in them. But this was often, but not always because they were produced before DB.
In my view, there is a place for duo cards on VGHD. But it should NOT be lesbian action in them. It should be just two girls frolicking about and dancing together. Lesbianism is adequately catered for on DB.
