In order for Skymiles to be effective, you have to have enough to use and use regularly, with 8K skymiles, you wont know if skymiles is a good program. All you know is you get the best price for the route you fly in the skymiles program, which is more important, at least to me. Maybe in the near future, when you travel more or collect more and get to use skymiles, you can judge for yourself.
I used to collect just skymiles, which is my highest FF program, but I now have over 200,000 miles each on all other major airlines program, for what I use skymiles for, it works well for me, but the program is not as good as others. So save any judgment on skymiles till you get to use it. It might work well for you and what you use it for.
