i think it depends on a number of factors including where in the country you are and what your individual "likes" or "wants" are.
I am fairly vanilla in terms of the actual sex but i am very picky on body shapes and what i find attractive. I look at many pics on here about "best this" or "best that" and usually think "no, she is awful" i like slim or petite and absolutely not fake boobs, fake lips or huge asses. Add in my age preference of under 30, my requirement for owo and where i live in the SW and there are few WG's that appeal to me.
so i would answer you question by saying "yes, for me, it is difficult to get a good reliable punt locally".
some guys rarely see the same girl twice - so for them there will always be more of a risk of a less than positive punt and of course because i see someone and have a good experience with them, there is no guarantee that you will.
