RCBO's or 2 RCD's

[eagleeye]

Hi Guys i am doing a job with a TT supply system would like your suggestions on weather to fit 30mA RCBO's on each final circuit or just a dual rcd split load CCU. I thought seperate RCBO's as the guy wants mains voltage downlights and we all know how many times it knocks the rcd out when they blow and also as i think that its better than a row of circuits trip off when only say a bulb blows. allbeit that itsgonna cost more money than the 17th edition dual split load

purely down to the cost
rcbos far better as you say
however much more money
