zaxxon - you're welcome Doug.
Kadri - sure, or better yet the cavity mask or a combi of both, or in conjunction with
Ulco's suggestion (mix several).
Dune - Yep, this was therefore the most promising freebie in my eyes. As for the blur
and mixing several I do agree.
DocCharly65 - Of course Nils, no problem.
Although a headstand might be a solution as well.

Thanks all, J.
