Why do some people choose 11" flexwatt and some will choose 3" for the same type of rack with the same type of snakes? I use 11" flexwatt for a 10 tub high cb-70 style rack with adults and 3" flex for a hatchling rack but im sure there are others out there who do things totally different when it comes to flexwatt.

i have been using flexwatt for a over year and am still pretty new to it. I would love to hear everyones experiences and ideas about multiple sizes of flexwatt applied to a variety of rack styles.

what works and what doesnt? What works best for you and why?
