David,
Imageclip is a very good laser transfer paper. Once you figure out how to press the two sheets and press the image sheet on the shirt you would be pleased with it. That is my transfer of choice. I do use inkjet and other laser transfer paper. My choice of inkjet transfer is Imageclip for inkjet.
Here is the procedure:
Material required - SILPAT brand Silicon cookie sheet with notched corners or other brand with at least one side with smooth surface trimmed off corners. Silicone sheet is available in department stores like Target and online from website that sells bakeware. I bought one that is chaper from Target. Note: The purpose of the silicon cookie sheet is to keep the papers from curling and its heat keeps the polymer from cooling down before the papers are peeled apart.
You can get the material from local Target store or online that sells bakers supplies. I have Silpat and and the cheaper brand from Target.
1) Press the two papers together with very light pressure at 210F temp for 10 seconds.
2) Open the press and immediately cover the papers with silicon cookie sheet with smooth side against the papers.
3) Make sure that the top left corner is exposed so that you can fold the corner of the red paper as shown below:

3)
Press again for another 10 seconds
4) Wait 6 to 10 seconds or count from 1000 to 1006 or 1010
5) Open the press, pick the corner of the red paper and peel the red paper with smooth even motion while keeping the silicon sheet with it and keeping the green paper in contact with lower platen surface.
Note: The picture shows the green sheet is in the bottom. I find that red is better on the bottom since it stays flatter on the lower patten. If the red paper is in the bottom then you pick the and peel the it with the silicone sheet instead of the red paper as described above.
6) Keep the red paper or the green paper (depending on which paper is in the bottom of the stack) and silicon sheets as close to the lower platen while peeling as shown below:

You need to post press the shirt for 6 seconds with image the covered with parchment paper for durability. I don't use teflon sheet when post pressing because a faint image will transfer on the it. If it is not wiped clean every after use the faint image will transfer on another shirt.
If you need further assistance send me a PM.
