When I replaced a old skill brand saw years ago with a t shank dewalt, the dewalt would not always cut straight with the base. I chalked it up with being a 'modern' piece of junk, and that is how new jig saws work.
I used to buy saw blades at the recommended tooth count blades and ones that had more teeth than recommended because I intuitively believed that the recommendations tooth count was too high. In practice, the recommended blades would break before they lost a substantial cutting ability. Wanting to get the most for the money, I usually used a higher tooth count.
On this project I decided to use a higher tooth count blade and interestingly, they cut normally and I did not have to force the saw sideways to follow my markings. Also I noticed, that if I actually kept my head further from the work piece, I could sort of 'get a larger overall view, and follow my lines better,less over correction I guess.
If anyone else has had these issues, i hope what I learned helped.
