When I sit my 510 down on the desk I always sit it down on it's side. I thought it might help the wicking if I stood it up on end letting gravity pull the juice down to the end towards the atty. I just crumpled up a piece of aluminum foil with a piece of paper towel inside to help prevent battery scratching. It's helped. Especially useful when you can only get a pull every 15 min or so...working in the shop, kitchen etc. The times when you can only pull a drag every once in a while. A juice glass, floral arranging foam for the ladies, anything would work. The foil conforms to any size or shape. I suppose the atty would flood if left for a long time or overnight but I haven't had a problem yet during the day. It's not the 'final answer' to slow wicking but it's helped me. Hope it helps someone.
