Need advice on steroid nasal sprays for seasonal allergy relief.

I suffer from severe seasonal allergies. I have been prescribed various steroid nasal sprays over the years. I have found that many of them cause a post nasal drip and give me a horrible soar throat. I end up feeling worse after one dose than before, as it adds to my symptoms. Currently, I am on the generic brand Fluticasone proprionate(50mcg), and I hate it! I am wondering if a brand name might be better. The one that worked best for me is no longer made, as it had CFC's in it and was banned many years back. Which ones might have the least side effects like this? Thank you in advance for your advice.
