Good luck! Hope it works out for you. There are always risks of course, but in the current market, keep in mind that it's highly likely that they need you more than you need them.
Without thinking through all possible consequences do not take any action which will jeopardize your status-quo. There is nothing wrong with your current strategy for your 1:1s. You should know your Manager very well before following "terryf"s suggestion; most Managers will not respond positively to somebody on their team who they think is "stagnating" (slacker, bad for team morale and growth etc. etc.). The worst-case scenario is, you get laid off while the best-case scenario is you never get a raise again.
