Hi Rob

Great review on the viper , my local Archery shop sells these beauties and have concidered one myself . Over in the UK it costs 93GBpounds and an extra 50GBpounds for the lens . Three questions though

1 > thelength of the sight armis quite long , whatare theadvantages over a short arm. There must be some advantage or reason . I use a toxonics 4pin with a stubby armand would i need a smaller peep .

2 > i will only be shooting 3D and field for now is the lens worth the extra money .

3 > i have limited experience in Archery and setting up . How easy is the predator to use .

Many thanks

Dave
