I've had about 30 dives on it
30 dives is not very many to be making a big decision about changing. I am not sure if your listed Total dive count is correct but if it is I would suggest the following:
1) Make 100% sure your weighting is correct for total weight & placement of weight.
2) Make 100% sure the shoulder & waist straps are tight
3) Spend 50% of each of your next 25 dives focused solely on hovering, balance, and trim.
4) Stop reading the internet and other peoples issues. You have no idea WHY those people had issues and many times people read something and try to make it fit their situation so they have an answer.
If, after those 25 dives, you are still having issues then consider making a change. My bet is doing the 1st three things I listed will show a great improvement in how the Hydros functions and the 4th one wil be great for your mental health. Wins all around!!
