I had a Samick Journey (same as Spyder XL) for a couple of years, and in that time I shot a sage a few times. My draw length is 29", or maybe a little more. And I could feel the stacking with the Sage limbs. If you already had the bow you could live with it, but since you are buying it I would get something that doesn't stack. A smoother draw is worth it.
If I was in the UK I would look at the Cartel version of the sage/spyder at Alternative Sporting Services.
The Cartel Epic Hawk is the same riser as the Spyder (which is the new version of the Sage). It is a 19" riser I believe. You may also consider the Cartel Sirius which is a 25" wood riser.
Either way you could get the Sirius Edge limbs for it. On the Epic Hawk riser the long limbs would make a 64" bow, and pick up 6lbs of draw weight. So if you want a 30lb draw order 24lb limbs.
If you were to choose the Sirius Edge riser then the marked limb weight would be accurate, and I would get medium limbs with your draw length. That would make a 68" bow.
Send them a message and see what you could put together, but that seems like a better way forward than getting a sage.
