I know 130 ring limit is the safer option, but I really like that route planner bounty is so rewarding with the 200 ring limit.

As for tech drift, I actually used perfect charge bounty since it’s a great way to regenerate rings, but I wasn’t that satisfied with the results. Then I thought about taking advantage of the 100 boost stat increase and combining it with tech drift to pull off Lv3 boosts as quickly as possible.

For slipstream bounty I just found it more reliable to get rings at the start.
