Hey rrowan, I am planning to use Smart Strings. However I have only been aware of this for less the 10 days, so I am reading as much as I can and trying to catch up. I have learned you need to fully understand what you are doing and how things work before you buy them or you may be in big trouble! I have miss some of the coops for now and will plan on the next ones. So far I am sold on DLA.
