Should i Install The Aviation Enterprises Wing Lets

[Skywalker]

I am completing my dream Sky Master 337 ;Pressurised model and in process of purchase, spotted out 3 planes ,two are in Europe and one In USA,All are ;H; model
My mission consists of 550 nm Trips over Apls with MEA of 16000 ft and in winter have lot of icing conditions, and as we know SkyMasters are not FIKI, I was thinking Winglets , are good choice as they will enhance my climb rate( as per claim) and let me climb faster if i encounter ice on the way up?i have no other wing extensions mods, standard 148 G tanks, was told by one of very respectful name and SkyMaster expert.. to stay away from them?
pls guide and advise, you guys can write me on skywalkerbellagio@gmail.com
or give opinion in this forum, thanks and blue skies
