I've been running an Echo urban for ages now (well over a year) and its still going strong. A couple of dents but nothing major, still true and its had loads of grinds. Well worth the money if you ask me. If it does seem a bit too heavy, single walling it will help shed a bit of weight without sacrificing strength too much.
Stick with a grind, these rims hold them the best, out of every rim I've ground.
Edit: on the topic of tyres, you cant go wrong with the Monty Eagle Claw, super soft with a good wear rate and its very bouncy. Plus, its slightly larger than a rear Creepy
