You say the 315 is too light, yet you're considering the 320, which is only 5 grams heavier. That's like the weight of one thin overgrip plus a rubber band dampener. It seems to me that if you consider the 315 "too light", then you would feel better with the 335.
true, also didn't notice that the 315 has a 18x20 set up as well.
