No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
I would pay it for 2 reasons. One, the NYS CRTP, it will be removed and it is the only way to see a score bump. Two, if you are getting a mortgage soon, you will need to disclose unpaid debt and they may make you pay it anyway.
Oh and a 3rd reason, if it is your only collections left you will be rebucketed into another bucket without collections.
Removing an OC TL can drop your score if it is your oldest account due to AAoA. I would much rather have a clean report than the lose of points from losing some AAoA.
You can lose points due to rebucketing or you could gain them. YMMV.
