another top job,
i think we're getting to the point where the word ricey no longer stands for DIY carnage, but hard work and determination.
you went against everything people told you about the work involved, and did it any way, but you saw it through to the end and did a stunning job.
and now the next time someone talks about doing their own plenum you'll say.....
pay someone else to do it
but as learning experiences go you can;t get much better than this kind of job; and i bet you learnt a lot
