Convex advice

I had end ileostomy surgery at the beginning of June, and my stoma was nicely budded so this whole time I’ve been trying flat wafers. But then about 2 weeks ago I started getting seepage and have been needing to change the wafer after fewer and fewer days—I can only wear a flat wafer for one and a half days now. I saw my stoma nurse who said that as it’s healed, it’s gotten smaller and though the top protrudes nicely, actually the bottom is not protruding as much and the opening / spout at the bottom is actually really close to my skin now. So actually I need a convex wafer now. But it’s time for me to make my first order with a supplier! And I have no experience with convex wafers. I’m trying a ConvaTec Esteem Body with only 3.5mm depth right now but the convexity seems to have disappeared after 24 hours because the wafer is so soft and I’m getting the feeling I’ll have to change it soon. Would a Sensura mio soft convex be like a next good step for slightly more firm convexity? I tried a Hollister soft convex by chance once and it hurt me so I’m trying to lean as soft and shallow as possible at first and slowly increase. I’m afraid I’m going to have to blind order without being able to try samples first… the Coloplast rep is mad at me already for having gotten too many samples so I don’t think I can ask them for any convex wafers. If anyone has experience with various convex wafers and could share that knowledge with me, I’d appreciate it 🙏🏻
