Default how to prevent scalloped surface with bandsaw

I prefer to cut Cellular PVC with my good Delta bandsaw rather than my cheap and dangerous table saw. However, despite my best attempts at keeping my feed steady, the finish cut has the scalloped look from the blade/feed. Currently, I am using an 8 tooth, .25 blade( from Lowes, I think it's a Bosch) that cuts like butter. In the past, wider blades burned wood and cut poorly. Should I go with more teeth,same width, or same number teeth but wider blade width for a smoother, cleaner surface.

I am cutting 1/8" thin strips, so I realize that there very little room for error.

I am ,however, happy with the finish. It's all jigged, so there little slop when I am cutting. I think there's room for improvement,though, thus my question.

A couple options, a blade with even higher tooth count can smooth out the cut, 12-15 tpi at least.

Other method which would give perfect cuts is to build a table saw crosscut sled. I don't know how I used to build some things "in the old days", now after using a sled, smooth, repeatable and very safe cuts, perfect for small items too.

Some have smashed the blade teeth in a vise to make a thinner kerf.

Never, under any circumstances, combine a sleeping pill and a laxative on the same night.

A good and right band saw blade should leave an even surface. I will get a quality blade and hope for the best.
If you are cutting a lot of thin material like 1/8" , then a high TPI number is appropriate. Check the instructions/manual of your band saw of what is a right blade width to be used.
