Spline Problem

I have 4 cylinders created that I would like to extend the 4 bottom .5 diameter tubes to the four sketched circles below. It can’t be extended in a straight line but needs to have a gentle curve.
What is the easiest way to go about this?

Here is the file for the issue.

One way is to use Loft. I copied your circles and moved then up in 3D space and gently increasing the distance from each other. Then I used Loft to create the curved tube. Note: this is a Q&D (quick and dirty) example of how this can be done.

Thanks for the quick response. Exactly what I needed.
