TOPIC: What can I do to limit my HA dissolving to the absolute minimum?

I love my thicker size but I'm wanting to continue to grow every year till I get to 6" Girth. But I'm at the point now that the wife and I have decided to do it only once a year to " maintain" and keep in budget. So my idea is if I can limit dissolving as much as possible I'll eventually get to my 6" Girth
