What next after 4wk Threshold and MAP blocks

I want to do another 4 week plan and my primary goal is to improve long MTB climbs. So far, I’ve done:
1wk HM/FF plan
4wk Threshold plan
4wk MAP plan
1wk HM/FF plan.
I saw a very nice increase in 4DP metrics after those 10 weeks . Now what? I figure it’ll be either another Threshold or MAP plan. Suggestions?
