i have a bbh multi fit and find its great. i still get the occassional leak but thats only if DS decides to have a really good wee or not with it on. it is huge on him tho lol. have you tried looking at second hand mcn's to try first? that way you aren't outlaying too much of a cost and if you dont like them you can always sell them on. also you only then need to buy a couple of different types and see how you go.

i also have a bumg mulitfit which came with a microfibre insert but i just stuff that with a bamboo insert and i find it fits him the best. so does the haute which is microfibre too. again i just boost that with a bamboo insert. both of these are pockets tho. so is the bbh multifit.

good luck
