Toughbox Nano Tube 31 Gear Drive

[JB]

I have recently been examining the Nano Tube Toughbox collection from Andy Mark. As a team who has been doing directly driven gear drive systems for the past few years, I think it would be extremely beneficial for our team to look at the three shaft, long, geared option seen here. http://www.andymark.com/product-p/am-0691.htm
Everything about this gearbox seems perfect to help our team reduce unnecessary build time during the first week or so of the season. My one concern with it is that one shaft is being power by one geared down cim, and the other two are also being powered by a geared down cim. Has anyone had any issue with this? I have also thought about making it a three motor drive instead of two by adding a fisher price with a reduction so that each shaft is driven by one motor. If anyone has any experience with the system and could shed some light that would be great.
