There's nothing wrong with an angled stem. I never understood the obsession with a flat and slammed stem. Too many people like to pretend they're in the pro peloton I suppose. You should just go with whatever is most comfortable IMO.

Get the rear-end of your bike perfected before touching the front though (saddle position relative to the cranks). Then it's a fine balance between stem length/stem angle/spacer height. Best of luck.
