1. What are the worst things about precise generation 1?

It has 6 cm limit right? But say you only wanted to do 6 cm on tibia (I think Parihar and Giotikas recommend 6cm or less on tibias)

2. Say you wanted to do internal tibia and internal femur w/ Giotikas. If stryde is not available, is it a bad idea to use precise generation 1 for tibia?

Its a bit hard to weigh the cost of precise 1 vs 2 and safety afforded by precise 2.2

Or is this all not practical b/c all or most of these has been recalled? Unsure if it has
