I can say this, I run a Fox Factory 34 and was 230lbs at the start of the season, I ride a Kona Big Honzo and I don't think I have used all the travel or bottomed out except maybe a minimal amount of time. I don't ride downhill, but do ride a lot of the rockier more technical northern parks. The 34 is a very solid fork, you may want to look into tweaking the settings, adding spacers or even getting it tuned for you.
On the other side hooray for new fork day!
