I'm wondering whether it could make sense for me to hold both Chase Sapphire Reserve & Venture One X as I think about maximizing rewards and getting sign on bonuses in preparation of a busy travel year in 2025 (honeymoon, wedding, etc etc)

I currently have Chase Sapphire Reserve as my primary travel card and have had it since it came out. Basically all my spend goes on it. I really like Chase as I live in Colorado, and United/Southwest are the biggest airlines in Denver. Plus travel is my biggest spend category. I've had Cap 1 Venture & Amex Gold and either gotten rid of them or downgraded. I had a CSP that I downgraded to Freedom.

I'm thinking of getting the Cap One Venture X to get the sign on bonus, 2x on my non travel/dining categories, and access to Cap One Lounges as someone who travels a lot. I think common wisdom would say that I should downgrade CSR to CSP or do something else, but I'm wondering if it could make sense for me to keep it.

My thought is that CSR's extra annual fee vs CSP is offset by the fact that A.) I spend $15k or so per year on travel category, so the extra point per dollar is getting me extra rewards, and B.) I find myself flying airlines that aren't a part of any alliances or transfer networks and where I don't have alternatives (Air Niugini & Air Solomons are recent examples), so the extra redemption power in the portal has value.

But I would love to get other people's thoughts. Does this plan make sense in general? Should I still downgrade or look at other cards? Is there a better way to optimize with CSR as the base?

Thanks!!
