I would highly recommend that you give Lou Fox (foxwear) a call and tell him that you are considering an eVap Wet Spring & Fall Jacket (
http://foxwear.net/products_jackets.html). He will explain the pros and cons of the fabrics and can make customized recommendations based on your riding preferences. I have been very happy with this jacket - kept me dry on my rainy commute in this morning. It is always a delicate balance between waterproof/water resistant/breathable and each person's choices are somewhat unique in this regard. To be fair, if it is a torrential downpour, the eVap will not keep you dry, but you can still wear it underneath a regular J&G waterproof rain jacket for those occasions. In my case, the eVap works for 98% of the rain that I encounter. Lou is a biker and knows how to make the perfect biking jacket. If you go with Lou, he will make a jacket that fits you perfectly.
