Dropping 50% EQM is a huge game changer to me. I switched from CO to WP in 2005 after CO copied DL's really bad idea. DL wisely dropped it as they retreated from the SOS gang but CO hung on for 4 years. I had heard they were firmly attached to it.
I flew CO last month and I have to admit I forgot how good their service is. Going to have to look at the possibilities now.
