Eleven new frames in an Abelo leaves about 5mm free at either end of the box, which is enough wriggle room to remove the second frame with ease (I never remove the first as it's the one most likely to roll bees) even if loaded.
I use eleven in Abelos all season long and without issue, but if you allow 3-4 mm. of propolis to build on a few Hoffmans then you'll always end up with a tight box.
Another essential: when you're done, close those frames up tight by levering the frames with your hive tool against the wall; if you do, the gap at either end of the box should return and propolis will be limited on Hoffmans.
If you want to use ten, the end frames will be built fat on the outside face to fill the gap; leave them and go for the second frame.
One of the benefits of that slight gap in the Abelo box is that it deletes the expense and labour of a dummy board.
