If you are questioning what to go with, you'll never be happy unless you try both. So go big, yes you will lose power with the 35's but once you get the 33's and relize that you wish you had gone bigger it's too late. Now if you get the 35's you may wish you would have gone with the 33's but at least you went for more than what you ended up wanting or needing. You know how it goes, most of our projects are neverending and once you get those 33's you'll be looking for more, just like when you first got those 31's and said you were happy with those, now look you're headed up already so just jump ahead 2 spaces instead of 1.
