johnblazevolkl mantra could be a good choice too
VÖLKL MANTRA M5
He will have some adjustment with tip and tail rocker and wider waist skis for all brands. RENT.
VolkI Mantra M5 - I tested it . or easier skis - like Volkl Kanjo, or a more regular ski like the RTM series....RTM have an 84mm and smaller waist
........The fifth generation of one of Volkl’s most popular skis had most testers writing love songs. “Ski absolutely railed through any conditions,” “Wow! This is an amazing ski! Easy to operate. A large sweet spot allows the operator to access the performance of the ski as well as to recover.”
the above is from Ski Canada Reviews
Or try the ARMADA ARV -The TI is stiffer, the others are waist width dependent performance. and softer ....
All of these skis have some camber -or old-school feel that he can carry fwd on.....(vs full rocker )
The narrower of these skis can do the east and the west - the wider skis (95mm +) are better left for the west
Get a shop that rents and lets you change up the ski mid day or alternate days......
