Be interested in how you find it Chris. A 16x10 frame full of capped brood is a joy to behold but I would be fibbing if I said I had never lost my grip on the short lug ends at least once. Particularly hilarious when it is the one the queen is wandering over.
Hence I often hold them partly by the top and side bars and ignore the lugs.
