My last CLI for my QS was on 04/19/2017 I did a request today and it was approved. It was only $500, but that's ok. on my Venture One I did a request at day 181 also and it was approved for $500. For data points.. I've been spending about 1K per moth on each card. I usually let between 0-8% report each month and then PIF the statement. Equifax is 730 overall Util 3%. Hope this helps...
