A 10 din binding would work pretty well and put you close to the mid of the range but most 10 din bindings won't be super burly but honestly at your size you will prob be ok. But you can go for a 12 din and they will be great for you. You will be down the bottom of the din range but that's fine, and they will last forever for you. Have a look at mojo 12, sth 12 driver or OS, px 12 ect there are a ton of good 12 din bindings as they are the bindings which people buy the most. Go chat to your local shop and see what they have deals on from last season if your trying to save money.
