When considering a new Hike & Fly wing, there are several factors you should take into account.
Skill Level: Is the performance of your glider properly matched to you skill level. Lightweight wings are often designed to accomodate many skill levels of pilots. Many "Mountain Wings," are lightweight designs of "Beginner" wings that are also produced in smaller sizes. Do not be lulled into a false sense of security just because you may be flying on what is certified as a low EN rated wing. Because you are potentially flying these wings with a much higher loading, the wings can become very dynamic and require a fair amount of skill in active piloting.
Primary use:Is this going to be your primary wing that needs to also be your multi-purpose wing, or is this going to be a specialty wing that will only be used for special conditions flying? If it also needs to function as your primary glider, a slightly more durable wing and one sized more "traditionally" to your weight will be the better choice. Also, if you have any aspirations for XC fying, a larger wing will most likely suit you better.
Performance Level: A higher performance wing will most likely weigh slightly more due to a more complcated internal structure of the wing. Also, when flying in locations like the Colorado Front Range, wind conditions can change rapidly and be gusty. A higher performance wing may give you the speed advantage to penetrate headwinds and cope with a wider riange of flying conditions, if your skill level is up to the task.
Pack Size: How much gear do you want to carry? How long is your hike? In Hike & Fly paragliding, weight and volume are your enemy. Light-weight/ lower performance wings pack smaller than equally sized heavier higher performance wings.
