If you are talking PPC Surges - 5.8m is more like a 6.5m - super powerful, the handles are really far apart on the 5.8m a problem if you are short, wingtips on this one often catch when pumping.
3.8 and 4.8 PPC Soars are excellent - they are more powerful than their size the 4.8 is prob a 5.5m in other brands, the 3.8 a 3.5m
Great wings and pretty tough - soft handles though.
Good for a first wing but personally after having used all the Surges for 12 + months, I would splash out a bit more for something with hard handles, they make pumping more efficient and far easier to swivel the wing around when doing transitions.
For $300 more you can get a 2023 4.5m unit which is more like a 5m
