Did you get samples?
If you did, put them in the sun on a hot day. We should be getting a few warm days before the weekend, I know its not 115. See if there's a temp difference. If the sample is large enough step on it in bare feet. See what feels better. I've seen a Benny on line with bamboo flooring. You probably have as well. If you haven't here's one

Did you think about aqua teak with snap in bamboo? I don't know if Bennington would do that and I also don't know if you'd like. You could also do bamboo up front and aqua teak in the rear. Did you also think that it is possible the aqua teak might do that again.
If I were in your situation, I think I would do the full boat in aged teak. I think the lighter color of the aged teak would be slightly cooler than the aqua teak... but, hey, it is your boat. I love the teak look, it looks clean and rich. Just my opinion.
Hope this helps, probably confused you more than helped.
