I posted a somewhat similar thread a while ago about my curiousness with spinners. I too prefer thickly woman and was more so concerned about seeing more petite ladies and spinners for a totally different reason.
It was titled "why you wouldn't see a spinner and why"

I posted it here......and ladies were pissed about it at the time here locally. But it was all too true for me...most of the time. Some guys will not speak on it. But for me trying to book multihours in other states and cities....there was always and issue for smaller ladies. They can't really handle a more spirited rump in large duration in the large majority. There are always exceptions to the rule sprinkled here and there, but I haven't heard anything about them in regards to overnights. And usually they have client restrictions either based on age, size, and race.
The rate is usually less promoting for multi hours as well. Usually little to no deviation for in rates the promotes or stimulates me wanting to book more hours. You will routinely see rates such as 300 1st hour, 600 second hour, 900 thirds hour........with no monetary incentive for more booked time attached. I will admit this. Spinners especially those touring usually are firm in their rates.....and don't offer discounts for more time booked. Moreso usually because they can't take much daily traffic and would prefer to maximize their daily quota and potential. Overnights can be taxing on the body and mind (sleepy), so some ladies supplement their rates with how much work they might miss.
But the overnight I book or moreso based off an all night fuckfest (7 hours active intermittently*3 to 5 bells*, and 5 hours cuddling and sleep intermittently) which I prefer......I stopped looking intently although when one is suggested to me by another hobbyist I trust I try to pursue those few.
I like the fact that spinners are compact, small, manueverable, and just usually in awesome shape position for position...you can experiment a lot. They are good trophies to looks at and marvel in their sleekness. But unless she's a spinner and thick as well I always concern myself with her multihour capabilities. An hour session or two is fine. But after About three hours session things start to change.....and I keep it to a minimum of two hours. They just can't take too much of a good rump in my opinion. So I try to stick with ladies slightly bigger. Ain't tryna hurt nobody........
