Strengthen Montesa Cota 247 front forks

[Niro]

what is the best way to strengthen the front fork (Cota 247 70'):

1. increase oil level
2. use heavier fork oil (current is 15w)
3. use spacers 
4. replace spring (the most expansive solution)

1. Tricky to get just right and increases seal friction.

2. Doesn't help to resist a long lasting compressive force like riding down a slope with the front brakes on.

3. If you have dual rate springs, increasing the preload will get you to the stiffer part of the spring travel sooner, but you may run out of spring travel before the sliders bottom and you may create a topping-out problem going up hills.

4. The best way.

Thanks. 

actually as you mention in 2, my main problem in soft springs/front shocks while going long downhill or in a very tight turns when I use front brake. 

Is there any recommendation for front springs? or the common ones, like In Motions sells will do the job?

About the oil, I just checked the manual and it says SAE 20/30 and I put 15. I guess I will go with the manual.

Is this price for one or pair? If for pair, it's good price.

Best to ask them.
