Nanoflare 800 – too difficult for me? Alternatives?

Hey
I’m on the road to get back into badminton after a decade long hiatus. I would either consider myself high intermediate or low advanced.

I bought a Nanoflare 800 as I heard great things about it, esp that it was so light and I have had issues with my supraspinatus that still bother me, so I heard people with similar issues used light rackets such as that.

I’ve been training about once a week for ~3 months and I can feel that I’m gradually getting back into things and improving slowly. But my consistency varies A LOT. Some matches I can feel that I’m hitting the sweet spot regularly, and five minutes later in another match it’s all over the place.

This week I got so frustrated with myself that I switched to an old racket (newly strung, like the nanoflare). The racket is a Forza Legend 80 characterized as mid-stiff, 86-89g, no info on 3u or 4u tho. I’m pretty sure it is ancient as I can barely find references of it online other than something from 2005. But it is made of high modulus graphite, so it is “modern” enough in that sense. Anyway, as soon as I started using this racket my consistency increased tenfold and I could actually reliably hit shots in the sweetspot.

I know the Nanoflare is a stiff racket, and the head is slightly smaller than the Forza racket – is that combination why it’s so difficult for me to use? And is the head size abnormally small?

It’s such a jungle to navigate with stiffness and head sizes that I just feel a bit lost and I’m not sure what direction I should go in terms of my racket…
