I do use blocks mine are quite large about one cubic foot compressed and dry. I use a putty knife to break it down to flat sections about 1 inch or so and then watch tv scraping the surface with it. Yes it is a lot of work but I don't mind myself but you can buy it in large bags loose and dry (hydroponics stores and greenhouses) You could always use water to deal with the blocks and mix in dry to reduce the moisture.
No sticking to the snake usually only lasts a few moments as they move about the will remove it and the coco absorbs the water so they get dry too. The only issue I have ever had with it is my largest female has once got a bit under a scale and it made a little irritated spot I just soaked her and it popped out from under the scale. She is very large, just over 6 foot and 3700 gms and has large scales none of the others have had anything odd. I have ha a couple of issues with wood chip types and personally will never use them again.
