as a beginner, when looking at wings, you should take into consideration (amongst other things such as instructor advise) the certification of the wing, it is not ideal because the tests are done for paragliding rather than paramotoring, but its the best we have at the moment.
EN Certification
A = Paragliders with maximum passive safety and extremely forgiving flying characteristics. Gliders with good resistance to departures from normal flight. Designed for all pilots including pilots under all levels of training.
B = Paragliders with good passive safety and forgiving flying characteristics. Gliders with some resistance to departures from normal flight. Designed for all pilots including pilots under all levels of training.
C = Paragliders with moderate passive safety and with potentially dynamic reactions to turbulence and pilot errors. Recovery to normal flight may require precise pilot input. Designed for pilots familiar with recovery techniques, who fly “actively” and regularly, and understand the implications of flying a glider with reduced passive safety.
D = Paragliders with demanding flying characteristics and potentially violent reactions to turbulence and pilot errors. Recovery to normal flight requires precise pilot input. Designed for pilots well practised in recovery techniques, who fly very actively, have significant experience of flying in turbulent conditions, and who accept the implications of flying such a wing.
DHV 1 = roughly Class A
DHV 1-2 = roughly Class B
According to this you should be looking for a
DHV 1 or EN Class A
DHV 1-2 or EN Class B
I do not know of any reflex wing that has a DHV1 or EN A certification, some semi reflex wings such as the ITV Dakota have managed a EN B in some sizes. The reason that reflex wings are not considered to be suitable for beginners (according to the testing) is because they are too dynamic in collapses.
This is where the argument starts where someone says, "reflex wings do not collapse, or are less likely to collapse, and the testing is not usefull for reflex wings"
