I would like to apply for the 60K Explorer card offer. The issue is that I already have 3 Chase cards and some with very high limits - a Freedom card with 30K limit, an Amazon card with 10K limit and a Sapphire Reserve with 10K limit so total 50K with Chase.

My concern is that Chase will scoff at opening another card and further increasing my total limit with them. Any experience with this? I am open to reducing limits on my other cards. But would like feedback on it.
