RE: How much will this matter?
Ok - cat amongst the pigeons time.
I totally agree with all of the previous replies given BUT
I know it is your first pattern meet coming up (is it this weekend or next weekend?).
If it is next weekend, try to get the Decathlon finished, maidened and sorted before the meet. (they don't take long to build - a couple of nights could see it done) Otherwise - take the dolphin and go have some fun. you are familiar with how it flies and You know it has a problem with regard to straightness but you will also be a bit nervous because of it being your "first time". Don't worry too much about your score at the first meet - just get the valuable experience from it.
"Journey of a thousand miles starts with the first step" - you will be as addicted as we are before you know it. (actually - it seems you are already on the way to that).
