Merits Of A Heavier Spring ?

I think the rear suspension travel for a 2014 is 164mm (check your handbook) therefore 90mm sag is 55% (90/164 x 100) which is far too much. You do need a heavier spring.

Since you are 96kg it looks like the splatshop 20% stiffer spring would be the way to go

You will also need to stiffen the forks a little, maybe more oil or spacer and if that is not sufficient, stiffer springs. Just a guess but a 25mm long spacer turned from polypropylene or nylon would probably do, but stiffer springs may be better, front is not so critical because it is often nearly unloaded but up gently sloped slippery rivers in particular a stiff rear and soft front will upset stability and loose grip.

So what am I looking for about 35% ?

I don't think splatshop do reiger springs, think its gas gas uk.

Depends to some extent on how you want the suspension to feel. A good rider who hits things hard and tackles big steps and likes to bounce the bike about probably has about 33% sag. Someone who rides the clubman or green course would probably be best with 35 to 40% sag. Too stiff is worse than too soft so don't go too hard.

Make of spring does not matter, so long as its the right inside diameter, not too large outside diameter and won't become coil bound at full compression it will be OK.

See above link. They would be able to measure your spring (including its rate / stiffness) and make you one to suit your weight. I have never used this company for motorcycle springs but their extension and "industrial" compression springs give good service and are well priced.

There may be a similar spring maker near you.

I bought a 75 spring for my Reiger and its good but I'll sell that and replace with the 85kg.
