deciding on sand or gravel

well i am using a black estes sand works good but really want to go with a lighter color. im thinking tan or brown just something that will really bring out the colors. i have been going through old threads all night and still cant decide. so here i am asking.
what brands of gravels is anyone using and please please post pics. i kinda want gravel as it wont stick but im still on the fence about it.
i also want to see some pics of people with sand. type, size and if it sticks to the rays.
im kind of looking at caribsea products torpedo beach, sunset gold, crystal river, and peace river. but that dosent mean i should get any of those. i havent seen many pics of the torpedo beach or crystal river though.
well any help is appreciated. so help me decide on the new substrate.

thanks pete i did see that. and was curious how smooth is the gravel? it kinda looked like it did have some edges on it. i think i will order it and put it in and if i dont like it then petsmart carries the sunset gold so i could always buy that also.

and fd your advice is worth alot more than 2 cents to me. i like the black but it seems like the rays are darkening up a little much. and im just not a huge fan of barebottom its just never been my thing. thats why im wanting to go to light colored sand or gravel.

im still looking for in tank pics of crystal river and torpedo beach though.

its not a big deal if no one posts im prolly going to order this tonight so its here by midweek. so how well do they bury themselves in it as my rays are on the small side i want to make sure that they have no problems.

ok sounds good to me. thanks for the input.
