Feeb I would probably try to avoid the H harness if you can at all. There has been a thread in here about it, not sure where and I am on my iPhone so can't find it. I personally had one and hated it, found it such a pita
Why was it a PITA??
I would like him in 5 point harness as long as possible and don't like the idea of just using normal seat belt. AHHHH why do we not have same standards as Europe!!!
