You may be seeing a common theme here, but we'll keep saying it. :)
What's best for you is the best choice for you.
In this case, the technical answer is sure: there's NO problem using a bandset that is wider than your forktip. You may lose a HAIR of oomph from the loss of elongation in the width of the bands that is not secured, but even then . . . just fold the band and you're all set.
In the end, if it bothers you, it will affect you, so don't do it if it's harming your mindset. But you will do just fine with wider latex than your forktip.
Pro tip: you may not need that wide latex at all! 😮
