I wouldnt try to ride it strapless to find a better front foot position.
I have had his boards since 2006, either standard or customized for my liking, and also ridden other boards.
So have lots of experience - rider weight can influence slightly yes, but not much for footstrap positions.
The front strap can be moved a bit, but mostly for personal liking as we are all a bit different.
Doesnt make sense to move it much, as there are a certain point where it just WORKS
If too far forward, a board will feel odd bouncing on the rail in fast bottom turns, if too far rear you will miss glide when surfing a wave.
Very important to find this sweet spot - but most often it fits with the std center or forward inserts on these boards.
But wont it be better upwind more forward?
No, as you will balance on the wrong part of the rail, you have to stand with rear foot further forward and a more narrow stance, and you have the best upwind style.
Rear straps has been too far forward for "centuries" (okay, maybe not but you get the idea), luckily they have gotten mounted correctly on some boards and brands now like on this one, great.
Strapped waveriding needs a very rear backstrap for full engagement in the curl, otherwise it doesnt work (except for beginners maybe)
Can it be too far back?
Yes, you will know when too far back, as then you will stall the tail into the wave/curl when you push hard.
It should work so you can push as much as you can, without having the tail "brake", but still dig in and spray max
I dont ride strapless anymore, no advantages and not appealing for me, so can not comment on this - but straps I have 16 years of experience on these very boards.
And other boards, but I have reverted to these boards, always.
Not saying I am right, just my experiences with straps, and friends riding boards like these.
The strap positions are the same both in knee high small waves, as well as big waves, no difference.
Some like a board like yours with a narrow rockered tail for small waves, as you can really turn on a dime and "embrace" the curl full on, just feels good
The price is you need to be more powered, or go slower upwind if not, and less glide.
Others like flatter boards, wider, for smaller waves - individual and everything works, just what you prefer.
You can also use bigger fins for a bit better upwind, but at some point it feels wrong when bottom turning at speed - you can feel when its wrong, fins starts to feel to lift instead of a clean smooth carve with the rails.
