Backscatter HF-1 versus Retra Pro Max II

dear fellows
I am just back from a short trip to Lembeh (8^th time in 27 years) where I took only 2 lenses this time : 90 mm Macro  and 20mm Macro1:2 (on a Sony A1 in a Nauticam Housing)

To pair with it I have only taken my Retra Pro X (2^nd Generation) and the Backscatter MF-2 for Snooting as I wanted to travel light for just 5 days of diving.

I left home my beloved SUBTRONIC Pro 270 that I usually use for (Ultra)Wide-Angle and Fisheye shots.

Very happy with all my Macro lighting with my set-up even for CFWA/Macro 1:2 (x0.5) with the Tamron lens as you can see below.

However, I realize I was missing power with the Retra Pro X for wide angle (20mm, no macro/distance shot) that iu usually get with my SUBTRONBIC powerful strobes.

Hence I am thinking of rationalizing my set-up and consider selling the Retra Pro X, rertirte the SUBTRONIC Pro 270  and buy either

Backscatter HF-1

Retra Pro Max II (last generation)

The price point of the Retra Pro Max II is really a barrier in comparison with the Backscatter HF-1. However, if I can travel lighter, that will be great given my age

Will appreciate all of your thoughts on my consideration.
