My Scorch/Fire Genin will earn these eventually at Chunnin or Jonin, the time limit is one post. And using the ability requires lots of chakra, to surround the body, go at very fast speeds, and try to cushion strain as much as possible. The strain of all the Gekirinkens (minus Mental Gekirinken) are huge and shouldn't be used more than once a day. Think Primary Lotus strain but a lot more.

I'm going to say no, because they don't fit with your Genin character in the slightest. That would be like a Hyuga learning Akimichi technique. Hyuga focus entirely on accuracy and movement while the Akimichi focus on brute strength and force. I won't say there OP, considering the weaknesses, and also considering other jutsu like 8 Tri-grams Rotation as their perfect defense for a short period of time.
