Staking on my new account

The Graveyard Help & Advice section is pretty dead it seems, I asked for help there and have gotten 50+ views, but no posts, so I figured maybe someone here could be a little more helpful. I'm currently working on a new account to try staking on since I failed horribly on my main. His current stats are 20 attack, 20 strength, 47 defence (will get 60 before I start staking), 38 hp (will be 49-50 before staking). When I get to my staking levels, I'll be 40 combat. Now my question is, when staking should I switch from accurate to defensive styles, or just stay on defensive (will probably be boxing). It just seems like by switching to accurate I will end up leveling attack too much and end up with higher combat than I want for staking, where as staying on defensive would take longer for levels to come in, and I could stay at 40 combat longer. I'm just not sure if I'll be hitting enough on defensive style to be able to outlast my opponents.
