Congrats mate.
My wedding ring has never been a problem, has been there ten years and not got in the way of anything much.
It's dead light though as it's made from titanium, to be honest I don't think it makes too much difference as once you've had yours on for a little while you'll stop noticing it.
Titanium has all sorts of benefits, it's feather-light, strong and possibly best of all, dead cheap! Mine was about £75 iirc.
