All,
Ed mentioned something while I was having a chin wag with him. (His accent in a little dfficult for me to understand, being English and all). Any way down to business, we need to Protect the probes.
I would recomend getting them to look over each other for any other obvious signs of wear and tear. Next we need them to work in some sort of buddy system. A bit like scuba diving. That way, when one of the little guys gets into trouble at least we will be able to evaluate the situation form another perspective and we will have a pair of claws at hand so to speak.
Any other ideas.
Love and light
