I use the Inset infusion sets, 9mm, 23". They are a 90 degree soft canula. I never tried anything else. I tried different lengths of the sets and found that the shortest length worked best for me. I have 1" button holes in each of my front pants pockets, along the front seams. I run the tubing through the holes to my sites. The pump stays in my pocket. There is plenty of slick in the tubing for me to take the pump out and make settings.
I have never had an occlusion in 9 months on the Tandem. I did have several pull-outs of the site when I first started due to my own clumsiness getting the tubing caught on objects. That has not happened since I had my pants modified since everything is inside my clothing. My pump is also safer in my pocket tun hanging on my belt.
I have never tried the Cleo sets. I like the compact size of the Insets I am using. I look for minimum bulk when I travel and the Cleo is larger. I amy ask my endo for a sample on my next visit just to try one, but I really like the Insets.
Oh, I did try longer tubing Insets, but found I had too much slack tubing to deal with and I never needed it so it was not worth the hassle of the slack.
When I change sites (every two days works better for me, but I have gone three days) I pull the site, wipe with alcohol, then put a small dab of Neosporin on the site and cover with a Band Aid. That eliminates any staining of clothing due to any small amount of site bleeding until it heals. Because I am on an aspirin regimen, my clot time is longer. I can usually remove the Band Aid after an hour. I have never had an infection and my endo likes my method.
