Have you tried Mount Baker Vapor's plain orange flavor? (Sorry, seems I'm too new to forums to be allowed to post links - google should have no trouble finding it for you.) I was looking for a good orange option, too. I tried a few flavors at my local B&M, but they were all orange with other flavors. I found them not orange-y enough for my tastes. Upon discovering Mt. Baker online I splurged a little buying some test flavors. I like their orange because it's not mixed with other flavors. It seems strongly orange, but pleasantly so, to me. I think they'll mix you up custom batches with added sweeteners and/or adjusted flavoring levels if you ask, but I've not tested this.
For references' sake ... mine is 80VG/20PG with 12 mg/mL nicotine, and I'm using it in a Kanger mega mow tank with a clonecores dual coil head which I rewicked with cotton. I'm also new to these forums and have been vaping for several weeks.
Cheers & good luck!
