Perfecting Trim

[llTritaTutto]

Hi yall, Ive recently gotten a new BC since last year June. Its seen about 20+ dives so far and Ive found I need some incredibly strange weight placement with 2 at the top camband and one just below my tank at my back.

Recently, Ive taken a huge liking for frog kick and been trying it out with my friend's eddy fins (I was told its neutral buoyant). In the attached video, this is a situation of my current trim. I feel the trim and frog kick form is okayish but i feel abit head heavy as when I tried back fin, I end up going back and upwards so im unsure if the trim is off or because I just suck at the form.

I understand fins can affect trim and I intend to change my fins to jet fins for frog kick. Im looking at the SP Jet fins, OMS Slipstreams, Eddy fins, Apeks Rk3 (a little soft for my liking), Tecline Jet fins or the Xdeep jet fins. If anyone has any advice/comments about my trim and what fins i need to balance it out etc, Im all ears

You might feel head heavy but you're head up in every one of those pictures. You're letting your knees drop in a couple too. I don't see that changing your fins would help. You might want to think about keeping a little tension in your glutes, so your body is flat from shoulders to knees.

Sorry may I ask what do you mean keep tension in glutes? Is it similar to like clenching the glutes when you do a push up/plank?

Clenching is probably too strong of a term, but you need a little tension in those muscles to keep your body flat.

Hey man, so my takeaways is I could have my tank too high up?

If you feel head heavy, you might be, even if your trim is positive - it's quite normal to counteract the feeling of tipping forward by bending and dropping the knees resulting in a head up posture. Whether you actually are head heavy, or just feel like it is hard to say, but some one-on-one with a good instructor or a class like GUE fundamentals should sort you out both in terms of technique and equipment setup.

Before doing anything else, deal with head heavy feel.
Keep perfectly still and see how you will be positioned.
Due to mask's field of vision limitations, people tend to be a bit heads up, even though they feel perfectly horizontal. Ergo, when you do get horizontal, you feel head heavy.
