Questions on using Podee bottles and teats with thickened Carobel milk feeds

Hi All!
For my 24 week LO have moved to Pepti Junior milk (no lactose and casien protein broken down) with Carobel thickener and Lansoprazole (PPI medication).
Feeding an absolute nightmare and only around every 5 hours so volume intake is a real problem.

Am seeking advice on bottles - I have used Avent up to now, but have purchased Dr Brown and a Podee bottle as alternatives but just trying to work out what teats to use with a thickened formula. Would like to try the PODEE first but dont know what teats to use.

If anyone has any experience of the PODEE or Dr Browns bottles and teats using a thickened formula, please do let me know!

Thank you, Best wishes, joanne
