To be honest I can't, didn't want trickle vents bloody horrible things, but they are a requirement in our building regs doc, we're not building a passive house but where we can improve the overall airtightness and control moisture around the openings EPDM was recommended as being a good option and as I understand it when the airtightness test is performed all the trickle vents are taped up. 

The way to avoid the need for trickle vents is install MVHR

We did consider an MVHR but the cost for us was prohibitive plus some of the reviews about them turned us right off them.

Any form of background ventilation is suffice, as long as meets requirements and controllable.
