As others have said, no reason not to talk to her. Until you have an accepted arrangement offer and schedule your 1st BCD, it's just hypothetical. If you get to that point, you will want to review all your options (or is it resources? Menu selections? Line up? How about stack?
and make some decisions about trade-offs or expanding your schedule.
But while you engage with her, keep in mind that you were not her first choice (or 2nd, or 3rd!) and presumably those POT SD's who were in the front of the queue either didn't qualify for her, or she didn't qualify for them. That's ok. It's part of the Sugar Dance. Just look to understand why/how she got to you, if possible.
And don't forget Papa Sweet's technique: Let her know your schedule is full, but you really want to stay in touch. He loses some POT's that way, but they were "lost" anyway, and he keeps the others "on deck" as pre-qualified for future opportunities.
Finally, you can always take her out on a test drive with a single BCD. That allows you to delay any schedule change decisions until you have more complete data on compatibility, performance, etc.
Last year, I had a M&G with a 30-ish Asian POT who lived within 4 miles of my home. We met and couldn't agree on some key issues: we were about $400 apart on allowance and she wasn't interested without hats for all activities. But she told me I had been the only guy she had met from Seeking that wasn't a total douchebag. We parted amicably without any future expectations. About 2 months later, she reconnected and after some discussion she agreed to all of my terms, as long as I could produce fresh test results on demand and I could not finish inside (despite my vasectomy results). I get tested monthly, so no problem.
We had about 5 dates and ultimately, I ended it (which if you know my preference for Asian women, you know was not an easy decision). My take: she had "settled" with me when she could not get the kind of money she thought she deserved, and I was the least objectionable non-ideal POT she had met. That showed in her shallow level of engagement outside BCD, and more importantly in near starfish-like BCD activities.
The lessons for me:
Never burn bridges (not a new lesson, just a good example).
Never negotiate against yourself by offering over your comfort level.
Never accept less than you want from an arrangement.
Life is good
