Which topstitching should I use?

I am finally getting down to sewing my tan linen Burda jacket. First I am making topstitching samples for which I bought a Schmetz double holed needle to use for topstitching. There are two holes one above the other. Unfortunately, my Viking doesn't seem to be able to pick up the upper thread. I made sure that the needle was seated properly, but no luck. So, I pulled out some 80/12 topstitching needles which I can double thread, but I am not sure that I like the results. I decided to use an off white Gutterman thread for contrast. I am not in love wtih the topstitching my Viking Platinum 750 does. It is not perfectly straight, so I don't know if I want to use the doubled thread, which just seems to accentuate the issue. Take a look and give me your opinions please.

I asked (reminded) my dd, Alex, to visit the fabric market in Seoul before she comes home to buy fabric for me. I figure I have to give her plenty of time; she comes home in September, this is her reply.

Dear Mom,

You make me want to cry. You know how overwhelming I find stuff like that. Tell me what you want and I'll buy it. I know nothing NOTHING about fabrics.

Love,

Alex

p.s. how much money do you want me to spend on all of this?

p.p.s. start thinking about what you want from china though i refuse to go fabric shopping in china, especially if i'm traveling without everett (ie no one to carry my bag). here at least i can bring Everett and have him help me carry stuff.

p.p.p.s. i think you are slightly evil. OBVIOUSLY THE BEST SOLUTION IS YOU START USING YOUR CHANGE JAR/WEIGHT WATCHERS MONEY WHEN YOU GET TO GOAL/SPARE 5 BUCKS TO SAVE UP AND VISIT ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

...i will go shopping for you. but plan on hearing me whinge about it. WHINGE i tell you.

p.p.p.p.s. i really miss you guys. like, not homesick ilke i Want to go home, i just miss you guys a lot. i'd like to see you. i can't wait until september.

I reminded her what a great mom she thinks I am and all the things I've done for her over the years. A little guilt can't hurt.
Here's a picture of Alex walking on the street in AnYang. I do love this one.
