Is that your only synchrony backed card? If so I would say go for it . My marvel is at 7000 right now , but I have a lot of synchrony cards so I am watching my overall exposure with them. If you have not had an increase in a year and you have mid 700 fico transunion score I would say your golden . It's a soft pull and the worst they can say is no. You can try chat or the automated system too for cli. I never had any luck with credit solutions surprisingly . Always have gone through chat or robo lady . I have seen this card get upwards to 25k. Let us know what you decide !
