Hi everyone advice on pastels

Hi, hope everyone ok, So thinking of trying the pastels, maybe the 10 10 or 5 0 i tend to use weak balanced strains, how long do these last and do you reckon a 10 10 eating a quarter a good start point? How long do they take to work? How difference is the experience. Also bmhoe do oils compare? I like that vape flower can be short lived if i Dont like. Please let me know any advice! Cheers 👍🙏
