Overkill grayd, that is not what he needs plus he wanted light
OK i am the same height and 10kg less (133 pound), i can ride anything but same deal i only like to ride light parts.
try and ride a 4.5 kg scoot that every kid and his dog buys then a 2.6 kg one that is specifically made for you alone... even 3.5kg to me feels off and that is a low weight for a "solid", aftermarket custom built for average riders, not kids. call me weak but i know what i want and how to achieve the ends.
District decks are a good choice for you;
weight
(the same as Promod, different balance;more front orientated on Promod)
mild strength but reliable
(unsure on new models but experience will most likely tell me nothing radically different has happened)
familiar feel
(razor pro model has close specs but more importantly, feels the same with a much more solid feeling and wider deck)
Decent price (when you compare mass razor products to say, any other mass scooter scooter specific companies; it's laughable)
Some other choices; links are provided so you can look.
Urbanartt
Trail deck
Ethic
Artefact deck
Unfair
BLVD deck
ALL above are lightest and closest to Razopromod in terms of feel overall
ALL else is not worth your time or money, these 4 including new districts are the cheapest yet better than more expensive ones.
(flavor can suck it, they make good grips and reasonable ti bearings nothing else IMO)
