I think people in general worry too much about the fabled tales they find online when researching credit.
Here's the deal... if you're not using it then ditch it unless it provides a significant benefit.
Scores are only a snapshot in time and you have aquired plenty of cards and now it's time to widdle down the stack for Quality over Quantity.
Your scores change as often as something is newly reported...daily, weekly, etc.
CSP 17.8K - potential for growth (whether SP CLI/HP CLI/New app and shuffle the CL's)
CHASE FU 7K - potential for growth (whether SP CLI/HP CLI/New app and shuffle the CL's)
REGIONS PLATINUM 4K - potential for growth
BBT CASH REWARDS 3.5K - potential for growth
BBT TRAVEL 3.5K - potential for growth
ELAN FINANCIAL 2K - depends on the program you're in vs Elan (servicer)
CAP1 QS1 1.5K - could be bucketed and stuck or just a starter limit and will grow
DISCOVER IT 1K - has growth potential
NFCU CASH REWARDS 700 - easily grows to 25K
This leaves you with some quality cards with significant CL's
40K+ w/ lenders that are solid, you have a 1 big spender card with CSP if something comes up that's a big ticket spend to keep your %'s lower than using another card, you have a rotator card (Disco) and potential if you wanted to shift CFU to CF for another rotator.
MY JEWELERS 5K
NEW COAST DIRECT 5K not sure what this is
KAYS 1K CREDIT ONE 500 OPENSKY 300
