If the POH says spins are prohibited, what is compelling you to want to expand the flight envelope. Have a lot of flight test experience? Have experience designing a flight test program? Asking on RAS for advice on spinning a glider that the manufacturer POH says is prohibited? No one has said it so I will
say it, What's wrong with you? And I say that with all due respect. When a glider goes vertical or beyond it can get to VNE fast. Spins can also turn into a spiral dive while you are applying anti-spin inputs. The POH on my ASH-26e prohibited spins so I never felt compelled to test fate. My Nimbus 4 I did not spin but I did do a full set of turning stalls and one accidental quarter turn spin. recovery from insipient spin is what is important. Watch below:

My Pegase 101's flight manual states that aerobatic maneuvers including intentional spins are prohibited.

I'm keen to test the behaviour of the glider in a spin and also the spin recovery procedure.

Is the Pegase really unsuitable for intentional spins, will the wings fall off?
