Ah, I just thought of another couple reasons why the sound isn't just the い->え change. I remember a long time ago someone telling me that another way to say すごい was すげー (of course, I only a year or so ago realized they were the exact same word ^^; ) Also, I've seen things like 行かない become 行かねー. I guess I'm wondering, is it just the last two vowels in an adjective that tend to get changed into えー? As in, 難しい would become something like むずかしぇー and 太い might become ふてー?
