Very true about the price the Synumn here in Oz is $300 but I got the Cartel here in Oz for $110 & best part for bows like Hoyt bows parallel limbs you can buy the adapter ( Synumn brand)I used the Bowmaster for all my bows up 'till my PSE with over parallel limbs. I found the Bowmaster seemed like it was just hanging on by its fingernails on the PSE limbs. The Synunm, although way over priced in the UK as it can be found in the USA for $99.99, has a better profile for keeping contact with the limb tips. It's dead easy to use and extremely quick. Because it's a continual pulley it can let the bow right down. It's a shame it's so over priced in the UK.
