The main bit of advice I could give you is to go into your bank and on the bottom right setup a log fletching preset and stringing bows preset. That way whenever you enter your bank you just have to press that one button (or keybind - they are keybind-able) and it will make your banking process even quicker. That will increase your exp per hour.
You are a member so make sure you are using a portable fletcher at all times, with your Fletcher's outfit for bonus exp.
Need help finding a Fletcher? Join 'Portables' FC and they will tell you where and on what world they're located. Or you could buy them yourself on the G.E but it will cost you a bit of extra cash. You're probably better off just using someone else's - they are usually pretty nice about it and it adds more sociability.
