I'm sub 20% in base Bus FO and I personally wouldn't go to the right seat of the 73 even though I'm 15%. I get what I want, but I also don't chase top tier 1 day trips. 30hr CUN layovers are cool, but I rather chase better quality trips in terms of sit times, report/release, etc. I'd rather have 30hr in CUN with my family than a crew (my opinion of course). So YMMV. Granted the trip pool in IAH on the 73 is a monster.
